Encyclopedia > Anubis (cipher)

Anubis is a block cipher designed by Vincent Rijmen and Paulo S. L. M. Barreto as an entrant in the NESSIE project. Anubis operates on data blocks of 128 bits, accepting keys of length 32N bits (N = 4, ..., 10). It seems that the cipher is not patented and has been released by the designers for free public use. Encryption Decryption In cryptography, a block cipher is a symmetric key cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation. ... Together with Joan Daemen, Vincent Rijmen designed the Rijndael block cipher, which was selected as the Advanced Encryption Standard in 2000. ... Paulo S. L. M. Barreto (born 1965) is a Brazilian cryptographer and one of the designers of the Whirlpool hash function, together with Vincent Rijmen. ... NESSIE (New European Schemes for Signatures, Integrity and Encryption) was a European research project funded from 2000–2003 to identify secure cryptographic primitives. ...


It is named after the Egyptian god of entombing and embalming, which the designers interpreted to include encryption. They claim that violators of the cipher will be cursed. In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge. ... Look up Curse in Wiktionary, the free dictionary A curse is the effective action of supernatural (or psychological) cause in an individual, group, or objects existence, distinguished solely by the quality of adversity that it brings, else it would be considered a charm or a blessing. ...

Advanced Encryption Standard - Wikipedia, the free encyclopedia (1661 words)
In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the US government.
The subkey is added by combining each byte of the state with the corresponding byte of the subkey using bitwise XOR.
It is interesting to note that many public products use 128-bit secret keys by default; it is possible that NSA suspects a fundamental weakness in keys this short, or they may simply prefer a safety margin for top secret documents (which may require security decades into the future).
