Signal is a cross-platform centralized encrypted instant messaging service developed by the non-profit Signal Technology Foundation and Signal Messenger LLC. Users can send one-to-one and group messages, which can include files, voice notes, images and videos. Signal uses standard cellular telephone numbers as identifiers and secures all communications to other Signal users with end-to-end encryption. The apps include mechanisms by which users can independently verify the identity of their contacts and the integrity of the data channel. The official Android app generally uses the proprietary Google Play Services (installed on most Android devices), though it is designed to still work without them installed. Signal also has an official client app for i OS and desktop apps for Windows, mac OS and Linux (although registration requires an i OS or Android device). Signal is the successor of the Red Phone encrypted voice calling app and the Text Secure encrypted texting program. The beta versions of Red Phone and Text Secure were first launched in May 2010 by Whisper Systems, All of these were proprietary enterprise mobile security software and were only available for Android. In November 2011, Whisper Systems announced that it had been acquired by Twitter. Neither company disclosed the financial terms of the deal. Some criticized the removal, arguing that the software was "specifically targeted [to help] people under repressive regimes" and that it left people like the Egyptians in "a dangerous position" during the events of the Egyptian revolution of 2011. In February 2014, Open Whisper Systems introduced the second version of their Text Secure Protocol (now Signal Protocol), which added end-to-end encrypted group chat and instant messaging capabilities to Text Secure. This announcement coincided with the initial release of Signal as a Red Phone counterpart for i OS. The developers said that their next steps would be to provide Text Secure instant messaging capabilities for i OS, unify the Red Phone and Text Secure applications on Android, and launch a web client. On October 4, 2016, the American Civil Liberties Union (ACLU) and Open Whisper Systems published a series of documents revealing that OWS had received a subpoena requiring them to provide information associated with two phone numbers for a federal grand jury investigation in the first half of 2016. Only one of the two phone numbers was registered on Signal, and because of how the service is designed, OWS was only able to provide "the time the user's account had been created and the last time it had connected to the service". On 21 February 2018, Moxie Marlinspike and Whats App co-founder Brian Acton announced the formation of the Signal Technology Foundation, a 501(c)(3) nonprofit organization whose mission is "to support, accelerate, and broaden Signal's mission of making private communication accessible and ubiquitous". Signal was reportedly popularized in the United States during the George Floyd protests. Heightened awareness of police monitoring led protesters to use the app to communicate. Black Lives Matter organizers had used the app "for several years". and video messages over a Wi-Fi or data connection to other Signal users on i OS, Android and a desktop app. All communications between Signal users are automatically end-to-end encrypted (the encryption keys are generated and stored on the phones, not on the servers). On Android, users can opt into making Signal the default SMS/MMS application, allowing them to send and receive unencrypted SMS messages in addition to the standard end-to-end encrypted Signal messages. The developers have stressed that this is meant to be "a collaborative feature for conversations where all participants want to automate minimalist data hygiene, not for situations where your contact is your adversary". Signal is integrating a system that lets users send and receive payments in MOB, short for Mobile Coin, a form of cryptocurrency. As of September 2021, the system is in beta and works only in Germany, the UK, France and Switzerland. This mandatory connection to a phone number (a feature Signal shares with Whats App, Kakao Talk, and others) has been criticized as a "major issue" for privacy-conscious users who are not comfortable with giving out their private phone number. The study concluded that 21 out of 28 participants failed to correctly compare public key fingerprints in order to verify the identity of other Signal users, and that the majority of these users still believed they had succeeded, while in reality they failed. Signal messages are encrypted with the Signal Protocol (formerly known as the Text Secure Protocol). The protocol combines the Double Ratchet Algorithm, prekeys, and an Extended Triple Diffie–Hellman (X3DH) handshake. The protocol provides confidentiality, integrity, authentication, participant consistency, destination validation, forward secrecy, backward secrecy (aka future secrecy), causality preservation, message unlinkability, message repudiation, participation repudiation, and asynchronicity. In addition to the properties provided by the one-to-one protocol, the group chat protocol provides speaker consistency, out-of-order resilience, dropped message resilience, computational equality, trust equality, subgroup messaging, as well as contractible and expandable membership. In July 2017, researchers from Ruhr University Bochum found during another analysis of group messengers a purely theoretic attack against the group protocol of Signal: A user who knows the secret group ID of a group (due to having been a group member previously or stealing it from a member's device) can become a member of the group. Since the group ID cannot be guessed and such member changes are displayed to the remaining members, this attack is likely to be difficult to carry out without being detected. as well as representatives from Signal, who said the original post by Cellebrite had been about accessing data on "an unlocked Android phone in their physical possession" and that they "could have just opened the app to look at the messages". Signal relies on centralized servers that are maintained by Signal Messenger. In addition to routing Signal's messages, the servers also facilitate the discovery of contacts who are also registered Signal users and the automatic exchange of users' public keys. By default, Signal's voice and video calls are peer-to-peer. In 2014, Moxie Marlinspike wrote that it is easy to calculate a map of all possible hash inputs to hash outputs and reverse the mapping because of the limited preimage space (the set of all possible hash inputs) of phone numbers, and that a "practical privacy preserving contact discovery remains an unsolved problem." In September 2017, Signal's developers announced that they were working on a way for the Signal client applications to "efficiently and scalably determine whether the contacts in their address book are Signal users without revealing the contacts in their address book to the Signal service." In June 2016, Marlinspike told The Intercept that "the closest piece of information to metadata that the Signal server stores is the last time each user connected to the server, and the precision of this information is reduced to the day, rather than the hour, minute, and second". Signal's server architecture was federated between December 2013 and February 2016. In December 2013, it was announced that the messaging protocol Signal uses had successfully been integrated into the Android-based open-source operating system Cyanogen Mod. Since Cyanogen Mod 11.0, the client logic was contained in a system app called Whisper Push. According to Signal's developers, the Cyanogen team ran their own Signal messaging server for Whisper Push clients, which federated with the main server, so that both clients could exchange messages with each other. In May 2016, Moxie Marlinspike wrote that federation with the Cyanogen Mod servers had degraded the user experience and held back development, and that their servers will probably not federate with other servers again. This enables interested parties to examine the code and help the developers verify that everything is behaving as expected. It also allows advanced users to compile their own copies of the applications and compare them with the versions that are distributed by Signal Messenger. In March 2016, Moxie Marlinspike wrote that, apart from some shared libraries that are not compiled with the project build due to a lack of Gradle NDK support, Signal for Android is reproducible. it received points for having communications encrypted in transit, having communications encrypted with keys the provider does not have access to (end-to-end encryption), making it possible for users to independently verify their correspondents' identities, having past communications secure if the keys are stolen (forward secrecy), having the code open to independent review (open source), having the security designs well-documented, and having a recent independent security audit. In December 2014, Der Spiegel leaked slides from an internal NSA presentation dating to June 2012 in which the NSA deemed Signal's encrypted voice calling component (Red Phone) on its own as a "major threat" to its mission of accessing users' private data, and when used in conjunction with other privacy tools such as Cspace, Tor, Tails, and True Crypt was ranked as "catastrophic" and led to a "near-total loss/lack of insight to target communications [and] presence". Following the 2016 Democratic National Committee email leak, it was reported by Vanity Fair that Marc Elias (the general counsel for Hillary Clinton's presidential campaign) had instructed DNC staffers to exclusively use Signal when saying anything negative about Republican presidential nominee Donald Trump. On the 27 September 2019, Natalie Silvanovich, a security engineer working in Google's vulnerability research team at Project Zero, disclosed how a bug in the Android Signal client could let an attacker spy on a user without their knowledge. The bug allowed an attacker to phone a target device, mute the call, and the call would complete - keeping the audio open but without the owner being aware of that (however they would still be aware of a ring and / or a vibration from the initial call). Signal received criticism from security expert Bruce Schneier, who previously praised the app, for its plans to add cryptocurrency payments through Mobile Coin. Schneier stated that this would bloat the app and attract unwanted attention from the authorities. In early 2018, Google App Engine made an internal change to stop domain fronting for all countries. Due to this issue, Signal made a public change to use Amazon Cloud Front for domain fronting. However, AWS also announced that they would be making changes to their service to prevent domain fronting. As a result, Signal said that they would start investigating new methods/approaches. According to CNN, "[t]he same technology that keeps a conversation private between you and a family member also gives a safe haven to a terrorist in Syria and the person in the United States he's trying to recruit to commit an act of mass murder." Signal is now developed by Signal Messenger LLC, a software company founded by Moxie Marlinspike and Brian Acton in 2018, which is wholly owned by a tax-exempt nonprofit corporation called the Signal Technology Foundation, also created by them in 2018. The Foundation was funded with an initial loan of $50 million from Acton, "to support, accelerate, and broaden Signal's mission of making private communication accessible and ubiquitous".We have come a long way since ECDIS was brought into our lives. In the initial days we were just struggling to keep the ENCs updated on ECDIS. Most of us know this drill at the back of hands now. And I have covered quite a few of articles on updating and keeping the ENCs up to date. Even during the third party inspections, the inspectors are now focussing on the ECDIS in detail. As even they consider that the period for amateur questions on the ECDIS is over. One of the area that now require detailing is the passage planning on ECDIS. Well, actually there is nothing different in the passage planning on ECDIS. More or less it is same as what we used to do on paper charts.
