Raw Blame History

// lea.cpp - written and placed in the public domain by Kim Sung Hee and Jeffrey Walton
// Based on "LEA: A 128-Bit Block Cipher for Fast Encryption on Common
// Processors" by Deukjo Hong, Jung-Keun Lee, Dong-Chan Kim, Daesung Kwon,
// Kwon Ho Ryu, and Dong-Geon Lee.
//
// This implementation is based on source files found in a zip file at the
// Korea Internet and Security Agency (https://www.kisa.or.kr/eng/main.jsp).
// The zip files was downloaded from the Korean language area of the site so we
// don't have a url or english zip filename to cite. The source filename from
// the zip is lea_core.c.
//
// The LEA team appears to have applied optimizations to functions in lea_core.c.
// The implementation does not exactly follow the aglorithmic description from
// the LEA paper.
