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. [1] [2] [3]
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 .
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 Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the top secret level, while the NSA plans for a ...
The Coppersmith method, proposed by Don Coppersmith, is a method to find small integer zeroes of univariate or bivariate polynomials, or their small zeroes modulo a given integer.
