In cryptography, Frogbit is a stream cypher algorithm developed by Thierry Moreau and is patented. Cryptography (or cryptology; from Greek grc κρυπτός kryptos, "hidden secret" and grc γράφω gráphō, "I write" In Cryptography, a stream cipher is a symmetric key Cipher where plaintext bits are combined with a Pseudorandom cipher bit stream ( Keystream In Mathematics, Computing, Linguistics and related subjects an algorithm is a sequence of finite instructions often used for Calculation A patent is a set of Exclusive rights granted by a State to an inventor or his assignee for a fixed period of time in exchange for a disclosure of an It includes a message authentication code feature. A cryptographic message authentication code (MAC is a short piece of information used to Authenticate a message It has been submitted to the eSTREAM Project of the eCRYPT network. eSTREAM is a project to identify "new Stream ciphers that might become suitable for widespread adoption" organised by the EU ECRYPT network ECRYPT (European Network of Excellence for Cryptology is a 4-year European research initiative launched on 1 February, 2004. It has not been selected as a focus algorithm nor for Phase 2; it has been 'archived'.
