● The cryptographic guarantees measure the level of security guaranteed exclusively by cryptographic measures (as opposed to simple access control). The custom cryptographic protocols implemented at the heart of Olvid guarantee an unparalleled level of security.
● The strong authentication evaluates the guarantees that the user has regarding the identity of his correspondents. It is impossible to make a communication confidential without prior authentication of the interlocutors. Phone numbers and emails are very bad identifiers! The authentication processes at the heart of Olvid have been designed with great care, since this aspect is central to any secure communication architecture.
● The server independence measures the level of trust to be placed in the servers to guarantee the proposed security promise. Olvid's is guaranteed even in the case of a malicious / compromised server. This aspect allows the backend to be deployed on any infrastructure, without worrying about confidentiality aspects. In concrete terms, this allows the issues of security and availability to be decoupled, making it possible to choose the infrastructure on the basis of the latter criterion alone. The quality of service that can then be achieved is superior to that of traditional solutions while reducing infrastructure costs.
● The anonymity measures the operator's inability to know "who is talking to whom. Olvid goes a long way, securing the metadata of communications as well, thus protecting strategic exchanges down to the smallest detail. It is not only a question of protecting what is said, but also who is talking to whom. In the context of a discussion about a merger-acquisition, for example, this guarantee protects against the leakage of confidential information that could impact the proper execution of the operation or influence the financial markets.
● Persistent confidentiality guarantees the confidentiality of the exchange history even if the cryptographic keys are compromised (e.g. if the phone is lost or stolen). Coupled with fine-grained management of data deletion on client workstations, this aspect allows Olvid to guarantee that an "old" document can never be exhumed. What is confidential today will also be confidential tomorrow.
● Security by design: so that the user can't make mistakes. Olvid reduces user errors to a strict minimum. In particular, all exchanges operated by Olvid are encrypted with the same level of security, with no possible errors. This avoids the pitfalls made infamous by some overly complex encryption solutions such as PGP.
● A multi-device software is usable on multiple devices at once (smartphones or desktops), with synchronization and without a master device. Our experience shows that the user himself is the primary cause of strategic data leakage, especially when he needs to access this data while not on the company premises. Olvid's cryptographic core has therefore been designed to allow the simultaneous use of several devices by the same user.
