ChaCha swMATH ID: 7098 Software Authors: Bernstein Description: ChaCha, a variant of Salsa20. ChaCha8 is a 256-bit stream cipher based on the 8-round cipher Salsa20/8. The changes from Salsa20/8 to ChaCha8 are designed to improve diffusion per round, conjecturally increasing resistance to cryptanalysis, while preserving—and often improving—time per round. ChaCha12 and ChaCha20 are analogous modifications of the 12-round and 20-round ciphers Salsa20/12 and Salsa20/20. This paper presents the ChaCha family and explains the differences between Salsa20 and ChaCha Homepage: http://cr.yp.to/chacha.html Related Software: Rumba20; Salsa20; eSTREAM; SIMON; Poly1305-AES; BLAKE; Keccak; Trivium; NOEKEON; CubeHash; CUDA; XTEA; SPECK; eBACS; Saturnin; GitHub; AEGIS; XooTools; Gimli; PRINTcipher Cited in: 36 Publications Standard Articles 1 Publication describing the Software, including 1 Publication in zbMATH Year New features of Latin dances: analysis of Salsa, ChaCha, and Rumba.
