serpent加密算法 8051汇编语言实现代码

Intel MCS-51 implementation of the Serpent AES cipher ----------------------------------------------------- Vincent Journot <[email protected]> Markus Kuhn <[email protected]> 2000-05-11 The files included are - serpent.asm: an 8051 implementation of Serpent in assembly language. It is public domain and should be used by anyone who'd like to see the performance of Serpent on 8-bit microcontrollers, such as in smart cards. The implementation covers only encryption. Decryption is left as an exercise for the reader. - serpent.pdf: an explanation of the implementation. - hare.asm: a faster implementation of Serpent but its code size is 7130 bytes instead of 2021 bytes for serpent.asm. Therefore you would find it difficult to load the code on some microcontrollers. - otheraes/: other 8051 implementations of AES candidates that were used for the performance comparison The assembler used was ML-ASM51.ZIP available from ftp://ftp.funet.fi/pub/microprocs/MCS-51/signetics-bbs/ The simulator used to test the implementation was the "535 Simulator" by Hernando Vasquez <[email protected]> and can be downloaded from: http://yo.mundivia.es/hvasquez/sim535/index.htm But, to be able to load a code whose size exceeds 1 Kbyte, you'll have to register.
