Crypto++ 8.2 Free C++ class library of cryptographic schemes

lea.cpp
1 // lea.cpp - written and placed in the public domain by Kim Sung Hee and Jeffrey Walton
2 // Based on "LEA: A 128-Bit Block Cipher for Fast Encryption on Common
3 // Processors" by Deukjo Hong, Jung-Keun Lee, Dong-Chan Kim, Daesung Kwon,
4 // Kwon Ho Ryu, and Dong-Geon Lee.
5 //
6 // This implementation is based on source files found in a zip file at the
7 // Korea Internet and Security Agency (https://www.kisa.or.kr/eng/main.jsp).
8 // The zip files was downloaded from the Korean language area of the site so we
9 // don't have a url or english zip filename to cite. The source filename from
10 // the zip is lea_core.c.
11 //
12 // The LEA team appears to have applied optimizations to functions in lea_core.c.
13 // The implementation does not exactly follow the aglorithmic description from
14 // the LEA paper.
