1.Citium提供哪些功能?

Citium Pro is the Secure phone Brand trusted by professional organization worldwide which allows you to communicate securely and deniably with other Citium users between any locations in the world, whether user is located inside information censored (firewall-ed) regions such as, China, Russia and Saudi Arabia etc or located outside information censored (non firewall-ed) regions such as US, UK, Japan etc.

Citium is secure Instant Messaging app pre-installed on Citium work phone which allow user to send and receive one-to-one secure text messages and allow user to join Unlimited number of one-to-many secure text messages chat groups. User could add other individual user or chat groups contact by:

1.  Scanning QR code which represent ID identifier generated by other Citium user; or 

2. Manually key-in a combination of "24 machine-generated alphanumeric digits" with "2 to 12 user-assigned alphanumeric digits as ID identifier provided by other users. All users could reset and change QR code or ID by infinite number of times without worrying other users may lost contact to him since the QR code or ID is a shadow identity that linked to their original ID identifier contact. Users could also temporary or permanently shut down QR code or ID identifier so no one is able to trace and contact them anymore.

Citium+ is secured group chat manager app pre-installed on Citium backup server phone which allow user to create, manage and edit only ONE chat group with Unlimited number of joining members, Citium+ backup server phone should always stay POWER ON and STAY CONNECTED to the internet in order for that specific Chat Group members to be able to exchange secure text messages. Citium+ backup server phone cannot read or send any secure group text messages except only allow to approve or deny chat group members' request to enter Chat Group. Citium+ phone could also serve as a backup server of your Citium work device, in case you lost Citium work phone and had paired it up to your Citium+ backup server phone before, you could simply purchase a new Citium work phone and help yourself pair it up one more time to your existing Citium+ backup server phone to retrieve any group contacts and conversations created from the lost device. A single Citium+ backup server phone is allowed to only host only ONE chat group, user who needs to create more than ONE chat group has to purchase more than ONE Citium+ backup server phone. If the Citium+ backup server phone owner, who is also the only Chat Group admin, wish to stop the created Group Chat temporary, he could switch off the Citium+ backup server phone or put it into the Signal Blocking Bag provided, Chat Group secure text messages exchange will be stopped and will only resume messages exchange until the phone is POWER ON and RECONNECTED to the internet again. If the Group admin decided to permanently dissemble the created Chat Group, he could reset the Citium+ backup server phone by pushing pulverizer button on the device, in this case, all group contacts and conversations will be permanently deleted, the backup server will also not be able to allow any work phone to recover any group contacts and conversations.

For Citium Pro Secure Samsung or Google Phone user (Apple iPhone version coming in late 2021), phone provided by us is installed with either Citium or Citium+ according to different phone plan selected upon payment. The secure phone device provided by us had locked down phone microphone, camera photo taking and video recording, all call service, SMS, MMS, Email, NFC, GPS, Bluetooth, USB C data port, biometrics facial and fingerprint sensor to use only with Citium instant messenger or Citium+ group chat manager. Our secure phone is equipped with a disaster control software button, Pulverizer, which if pressed, could wipe out all your communications records and contacts in case of emergency. Once pressed, Pulverizer will irreversibly remove all data from Citium phone, apps and networks. (*在這裡查看安全手機*。)

Each single phone device above comes with Dual (two) secure international roaming SIM cards without any personal identifier attached to the SIMs, all SIMs had went thru security check, inserted into the Phone SIM slots and sealed with Citium secure holographic labels on phone and packages before shipping, ready to be turned on and ready for use.

Depends on phone plan selected, it comes with either single or dual Citium Faraday wireless signal blocking bag(s), when the phone is placed inside the bag with power on or off, all cellphone wireless signal is automatically blocked (e.g. 2G to 5G, WiFi, GPS, bluetooth, and NFC) and your wireless footprints exposure risk is minimized. The phone(s), SIM card(s) and Faraday bag(s) is shipped worldwide by International Priority shipment tracked. 

2. Could Citium free users from eavesdropping and surveillance?

Yes. For instance, in 2013, whistleblower Edward Snowden revealed the US NSA PRISM surveillance program (https://en.wikipedia.org/wiki/PRISM_(surveillance_program) to the world. We cannot face the reality without learning a lesson from it that everyone is subject to eavesdropping, surveillance and even coercion. What Citium does, paradoxically, is to offer deniability so that eavesdropping and surveillance is rendered meaningless because no one knows for sure who sent what from which devices in the vast ocean of "bottles of messages'' hidden in the plain sights of the Citium network of nodes. In other words, Citium utilizes a blend of deniable encryption schemes so that eavesdropping and surveillance become innocuous if not entirely inconsequential. **In most circumstances, coercion is tantamount to total defeat. Your attempts to protect the confidentiality of your communications have been in vain.** The purpose of deniability is not at all to “convince” the coercer that any surrendered transcript is real; indeed, it is common knowledge that transcript can easily be faked. Instead, **the goal is to preempt coercion in the first place by making surrendered transcripts useless**. Citium user(s) simply have to “stick to their stories”. No data analyst or forensic expert can irrefutably prove who is involved in which message in Citium. The use of Citium has enabled a major paradigm shift to deniable encryption schemes as the last defense of confidentiality. Simply put, as long as you communicate through Citium, you are free to deny every evidence against you. It is not your duty to prove that you are innocent. It is someone else's duty to prove that you have done something wrong that leads to your charges. But rest assured that no one is capable of doing so.

3.如果有人擁有無限的時間和資源,他們是否可以破壞整個Citium網絡,使用戶陷入危險境地?

No, because Citium secure text messaging is always available even if all the other Citium nodes have been taken down because **dynamic transmission of Citium data piggybacks on BitTorrent and Bitcoin networks**. Yes, you heard correctly. Not only that Citium has no central servers, which essentially renders raiding, shut down, or forces to turn over data impossible, but also that its data transmission relies on P2P network infrastructures. Thus, say goodbye to the server and node outages! A threat actor needs to physically seize ALL devices, such as phones, routers and content servers in ALL countries, where the Citium nodes are situated, to hamper the performance of the Citium network in transferring secure text messages. Not to mention that the takedown is not only highly improbable but a glaring act bound to draw attention. It is just too Pyrrhic for most of the threat actors to contemplate. In contrast, law enforcement who is targeting popularized secure chat service, such as EncroChat, would only require a one-time, yet discreet, takedown of their centralized messaging relay or contact directory servers. Most users may unknowingly continue to use the service while their IDs and data have already been covertly compromised. Luckily, Citium users never have to worry about this kind of mishaps. The number of connected device nodes in the Citium network are only growing day by day because every online Citium client app is an active node that serves itself as well as everyone else in the decentralized network. Therefore, **crippling or compromising the Citium decentralized network is only getting geometrically harder and harder as time passes while centralized service providers, such as SkyECC, inevitably heighten their data breaching risk as they gain in popularity**. Technically, in the Information security sense, the decentralized network of Citium nodes is a layered defense on top of the PGP-encryption scheme, making Citium communications deniable and quantum-safe. This is a unique service unavailable by any other provider.

4.當我使用Citium時,我會不會暴露我的IP位置或對話?

No, because we have IP obfuscation (IP mask) technology to mask your IP and location. Ordinary cellphone device could be traced by Stingray phone tracker but not Citium secure phone. For example, someone using their private daily cellphone could be tapped by Stingray which pretended to be your mobile cell phone tower, thus intercept and obtain your device identifier like IMSI and ESN to calculate your real location or tap into your conversations and this is not safe. The safest practice for you is to use a Citium Secure phone, Dual secure SIM card(s) and Citium Faraday bag. When you are done with your Citium communications, put your secure phone back into the Faraday Bag to minimise the time your device is exposed to cell phone signal. Citium is designed to keep you safe from harm when things get heated . Ever heard of someone walking out of court with all charges dropped? That is how Citium could help. Of course, a good lawyer always helps, too.

5. Where and when could you use Citium Pro Secure Phone? Where does Citium secured phone, secure SIM card and Faraday Bag be shipped to?

You could use Citium Phone in every countries or regions at all times with access to internet connections, be it 2G, 3G, 4G, 4.5G (LTE+) and 5G or even open WiFi stayed inside or outside Information Great Firewall. Citium Secure phones, Dual Secure SIM cards and Citium Faraday Bags are shipped worldwide with the International priority shipping charges included in the price tag. We offer you non identity bearing SIMs that covers following countries and regions. But even without using our secure global roaming sim cards to connect you to your local cellular network, every users in every countries and regions could still use Citium and Citium+ phone securely under any Wi-fi environments, be it public or private Wi-fi.  You could expand the list below to check for the 184 countries and regions covered by our Global roaming Secure SIMs:

6. What about Global roaming data plan of SIM cards? Can I still surf the web or use other apps when I use Citium?

No, for security reasons we do not allow browsing of websites or use of any apps except Citium apps. All phone users have unlimited global roaming data dedicated only to the use of Citium apps on our secure phone. For security reason, all SIM cards provided by us could not be taken out or be used outside of any Citium Phone, any SIM(s) removed from secure phone would automatically void by itself and had SIM PIN locked. User had to contact our CS and to pay for a replacement SIM with an additional cost of shipping charge for SIM(s). USER ARE STRONGLY DISCOURAGED TO TAKE OUT ANY INSTALLED SIM CARD FROM THE SECURE PHONE DEVICE. With Citium apps uprunning, we need your VPN permission on phone device to run our apps that means you are not allowed to use other VPN service when Citium app(s) is uprunning. All plans come with Dual (two pieces) global unlimited data roaming sim card, our SIM cards are for roaming data only and no phone number or extra value added service is associated with any SIM card, this is security measure to eliminate any phishing or temper attempt to the SIMs . After payment is made, please register your Citium account with the disposable email provided on the page, login Citium Membership system (CMS) and fill in your shipping detail, If you decided not to receive our SIM card(s), please check "I do not need any SIM card(s)" in our CMS after payment, in this case, you gave up your rights of having our SIM card(s) and you could not claim your SIM card(s) again for the rest of your phone plans subscription period, otherwise, our SIM cards will be properly placed into your phone SIM Slots, sealed and to be shipped with your phone order.

7.為什麼要建設這個Citium網絡,使用它是否合法?

向所有記者、科學家和所有維護真相的人致敬。我們相信信息自由的權利應該由所有人擁有。使用Citium保障你與生俱來的人權不受侵犯,並沒有任何違法之處。

8.Citium是否有可能被非法使用?

同樣,不管有沒有Citium,所有的通訊工具都可能被非法使用。在街上違法後被抓比使用Citium被抓要容易得多。重要的是用家背後的意圖動機和行為,而不是通訊工具本身。

9.為什麼要相信Citium,Citium怎麼能證明自己的技術完整性?

沒有證據比網上社區對我們的評價更好。我們的設計在GitHub中完全開源,任何人都可以查看。你可以找到它 (這裡) 我們發表的關於密碼學和安全的研究成果也可以在這裡找到 (這裡) Our App and networks are battle-tested in many countries and optimized after extensive testing, our secure phone keep you updated with the best security updates and is safe to use even in extreme environments.

10.為什麼Citium會是這個定價?

自由是沒有價碼的,雖然我們力爭在未來把服務成本降下來,但還有一段路要走。我們是一群狂熱的信息科學家和愛好者,他們既在實驗室又在街頭,知道如何把事情做好。

11.Citium與市場上的其他即時通訊工具相比如何?

免費的應用程序,如Signal、Telegram、WhatsApp、Facebook Messenger,微信,電子郵件、短信或電話等方式,獲取並使用至少一個個人標識符來跟踪你。它們可以追踪到你的真實身份。這些公司的隱私政策決定了他們的用戶信息是不安全的。更糟糕的是,他們集中管理的商業模式使他們容易受到脅迫。這意味著他們更願意為了自己的利益而洩露你的信息,因為他們有權在未經用戶許可的情況下向第三方發布用戶信息。另一方面,付費應用,如SkyECC,會將用戶ID分配給你,因此任何擁有你ID的人都有可能找到你並試圖敲你的門。 Citium通過以下方式保證您的隱私: 不要求 for anything about you from the process of payment, installation and to customer service. Even our customer service representatives do not know about your existence unless you actively reach out to us, which means no one in the world could contact you without your permission. A private e-cert is generated and welded to your phone device when you first launch Citium apps, instead of using old-schooled user ID and password which proven its weakness. It will free you from username and password combination leaks, ID theft, device and apps phishing, malicious random ping of messages hack and trash ads. We have no central server so any DDoS attack or attempt to data kidnapping is, by design, impossible. You are the only one who controls when, how and with whom you are chatting with.

Apart from privacy issues, from the encryption algorithm point of view, all those free apps on the market issue the public keys that their users use to encrypt the messages so that the those free apps companies know who the users are simply by knowing who's using which public key. In contrast, each Citium user issues his/her own public key. In fact, every one of your Citium Contacts are communicating with you through some proxy accounts which Citium created for your Contacts individually during out-of-band verification meaning you could exchange Citium QR code or alphanumeric ID Identifier with others using any Instant messaging Apps or social media platforms in the markets safely. Your Contacts do not know if the accounts are only for them or they're for someone else as well. This scheme essentially disallows your Contacts from turning against you in the future because they cannot prove irrefutably that they are talking to you. Everyone talks through "sockpuppeting accounts" which no one knows for sure who's talking through them so that everyone in Citium can maintain plausible deniability at all times.

12.為什麼我觀察到通過Citium收發信息偶爾有延遲?

The short answer is that the occasional delay is the price we pay for the extra peace of mind in security. The extent of a delay highly depends on the size of a message. If it is just several secure text messages, which is small in number, the delay will normally be resolved in a few seconds. While you are waiting, Citium is busy encrypting your message with a triple layer of encryption, namely ECDSA, BLOWFISH, and XXTEA. Notably, ECDSA is the encryption scheme used by the Bitcoin network, which has stood the test of time. As the market capitalization of Bitcoin is already in the hundreds of billions of dollars, cracking even a fraction of it means jackpot or attestation to a hacker's ability. In spite of the incentives, no one has been able to crack it. The only reason why ECDSA has not been adapted more widely is due to its hunger for computational power. Mobile devices need time to process the encryption which contributes to the occasional delay. Furthering the delay is the casting of sliced ciphertexts to the P2P networks (i.e. Citium, BitTorrent, Bitcoin) because the ETA in decentralized systems is not as predictable as those in centralized ones. Not to mention, all the while the recipient end is busy fetching these tiny encrypted pieces of message, then decrypt and reassembling them back to the original, readable format. The transmission process is slower than most of the other instant messengers but it is the necessary performance and security trade-off for Citium users who value confidentiality above all. Technically, the slicing of messages is a concept in threshold cryptography which makes Citium post-quantum resistant. In plain English it means that even threat actors who come back from the future, armed with quantum strength deciphers, cannot reveal the original text.

13.好吧,我被Citium的能力說服了,說說Citium做不到的事情,完成我的交易吧?

Citium does not support voice clips, pictures, video clips by the moment. And Citium permanently does not support real time live-stream data, such as VoIP voice chat, FaceTime and video-conferencing because point-to-point real time connections pose insurmountable privacy risk, potentially compromising your identity and geographical location, defeating the purpose of plausible deniability. But that is all right because there is nothing preventing you from bringing a personal second device own to go live-stream for your casual communication. Also, note that the polar opposite of deniability is non-repudiation, which Citium cannot offer. Non-repudiation is an InfoSec feature required by the kind of communication whose accountability supersedes confidentiality.

14.Citium的隱私政策是什麼,如果你認為Citium不適合你的需求,你能不能得到退款?

Citium server nodes are open source, allowing you to view the source code, and is monitored by the open source community to ensure that the source code is free of Trojan and does not reveal any user information. When you contact one of our customer service representatives, please do not leave us any personal information. Our customer service representatives will not ask for any personal information about you. Your e-Cert is you, and you are the e-Cert. We only communicate with the holder of the e-Cert, and only through the LIVE CHAT interface within the Citium apps. Likewise, if you lose your e-Cert, your account loses any chance of recovery and all information is lost forever, unless you had purchased a Citium+ backup server secure phone where you could recover your contacts and conversations. All transaction payments are final and non-refundable under ALL circumstances. This is to eliminate any refund phishing attempts that may reveal user information.

15.當您決定停止支付服務續費時,您的賬戶會發生什麼情況?

We respect your decision of not renewing further. When you decided not to renew the phone subscription, you will NOT be able to open Citium apps in your device. Your in-app contacts and messages are permanently unrecoverable. Citium is, by design, permissionless so that it is impossible for us to delete your account remotely. Only you can delete your account by pressing the disaster control button in your Citium app which will eliminate all communications and contacts in Citium. The other way to look at it is that if you lose your device or accidentally press the disaster control button, you will lose access to your account and everything inside, such as contacts and messages. There is nothing we could help about that. Depends on your latest app settings, all information will automatically be deleted and disappear at a minimum of 3 days or a maximum of 30 days. 

16.Citium能否恢復或恢復用戶在Citium應用中刪除的信息和聯繫人,Citium的數據隱私政策是什麼?

No, Citium cannot revive or restore messages and contacts that users have deleted or lost access in Citium's app, nor could anyone does. Citium does not keep any of your data, you do not need to provide phone number, sms or even personal email for registration and subscription so that is truly an anonymous account. We do not keep any messages you sent and receive, this is to make sure both you and us are safe when we are forced by someone to give out any data. We cannot give out any data simply because by design we do not have the ability to keep your contacts and communications at all. For contact verification, everytime you add someone into your contact, a single time disposable encrypted key is generated so you could send it over to someone, no key is used twice, without the key, you cannot add someone, same goes, without the key, no one could add you. Even if a key is presented by someone, you could still choose to accept the invitation or not. You could set and keep the same username or set a different username to be shown for each individual contact, someone could also rename in their Citium contact about how they liked you to be called. Our metadata policy is simple and straightforward, we do not keep your data.

17.如果Citium的網絡速度很慢或者出現故障,用戶是否可以要求賠償損失和/或損害,或者提出投訴,或者投訴應該去哪裡?

When you use Citium, you are granted automatic waiver from any claim of direct and/or indirect loss and/or damages in all circumstances. Our goal is to maintain Citium uptime to at least 99.99%, but you should understand that the Citium network is decentralized and affected by open network performance, policies and many more conditions in different countries. Network congestion or failure may occur at some points. Please report your connections downtime or improvement suggestion to [email protected] or tell us what you think via our social media channels. We are always listening. Our team always strives to serve the user community better.

18.我在社交媒體上聽到一些傳言,黑客 "%xyz# "成功入侵了Citium用戶之間的安全對話。

19. How do you check the subscribed Citium phones, apps, global roaming SIMs and networks are genuine?

1. Check if the arrived phone packing are sealed with Citium Holographic Secure Label, before you remove the label, do you see "VOID" appeared under the security label on phone packing, if "Yes", refuse acceptance on site and return it to shippers; 

2. If you had opened the phone packing already, before remove the Citium Holographic Secure Label, do you see "VOID" under the security overlay the Phone SIM slot? If "Yes". Stop using the phone and contact our website frontpage CS immediately.

3. When you turned on the phone for the first time, do you see "Enter Citium" button appear on Citium App frontpage? If "No". Stop using the phone and contact our website frontpage CS immediately.

4. When you have followed instruction to completed your ID setup for the first time, try scan the following QR code, is your request not being accepted for more than 24 hours? If "Yes". Stop using the phone and contact our website frontpage CS immediately.

20. Could I resell Citium or become a distributor of Citium?

請聯繫我們:[email protected]

更快、更好的方法,請通過Citium應用內CS聯繫我們。對於社交媒體帖子的任何延遲甚至沒有回應,我們深表歉意。我們正在投入所有的資源來打造更好的服務,並照顧好現有的用戶。我們更傾向於口碑等有機增長,並決定在可預見的未來保持這種方式。
