Off-the-Record Messaging, a cryptographic technique providing true deniability for instant messaging. OpenPuff, freeware semi-open-source steganography for MS Windows. StegFS, the current successor to the ideas embodied by the Rubberhose and PhoneBookFS filesystems. Vanish, a research prototype implementation of self-destructing data storage.
In cryptography, deniable authentication refers to message authentication between a set of participants where the participants themselves can be confident in the authenticity of the messages, but it cannot be proved to a third party after the event.
Plausible deniability is the ability of people, typically senior officials in a formal or informal chain of command, to deny knowledge and/or responsibility for actions committed by or on behalf of members of their organizational hierarchy.
Off-the-record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function.
The protocol offers forward secrecy and cryptographic deniability. It operates on an elliptic curve. [16] The protocol uses five public keys. Alice has an identity key IK A and an ephemeral key EK A. Bob has an identity key IK B, a signed prekey SPK B, and a one-time prekey OPK B. [16]
In cryptography, the Double Ratchet Algorithm (previously referred to as the Axolotl Ratchet [2] [3]) is a key management algorithm that was developed by Trevor Perrin and Moxie Marlinspike in 2013. It can be used as part of a cryptographic protocol to provide end-to-end encryption for instant messaging .
In cryptography, forward secrecy (FS), also known as perfect forward secrecy (PFS), is a feature of specific key-agreement protocols that gives assurances that session keys will not be compromised even if long-term secrets used in the session key exchange are compromised, limiting damage.
Cryptography is the practice and study of encrypting information, or in other words, securing information from unauthorized access. There are many different cryptography laws in different nations. Some countries prohibit the export of cryptography software and/or encryption algorithms or cryptoanalysis methods. Some countries require decryption ...
