CubeHashとは 意味・読み方・使い方

CubeHash is a cryptographic hash function submitted to the NIST hash function competition by Daniel J. Bernstein. Message blocks are XORed into the initial bits of a 128-byte state, which goes through an r-round bijective transformation between blocks. The initial NIST proposal ("Cubehash8/1") required about 200 cycles per byte. After some clarifications from NIST, the author changed the proposal to Cubehash16/32, which "is approximately 16 times faster than CubeHash8/1, easily catching up to both SHA-256 and SHA-512 on the reference platform" while still maintaining a "comfortable security margin".
