Submitter: Ross J Anderson 
Algorithm: SERPENT 
 
Reference ANSI C implementation (unoptimised) 
============================================= 
 
This floppy diskette (#1) contains the following files: 
 
  Makefile 
    rules for building and testing the C files 
 
  serpent-api.h 
    NIST API header file adapted for Serpent 
 
  serpent-tables.h 
    tables for S-boxes and linear transformation       
  serpent-reference.h 
  serpent-reference.c 
    serpent core implementation 
 
  serpent-aux.h 
  serpent-aux.c 
    auxiliary functions that print and perform conversions 
 
  serpent-test.c 
    very basic command line test program 
 
 
NIST-specified tests: 
 
  ecb_vk.c 
    variable key 
  ecb_vt.c 
    variable plaintext 
 
  ecb_iv.c 
    intermediate values 
 
  ecb_tbl.c 
    tables 
  ecb_tbl_precomputed.txt 
    Input data for tables test, as generated by the Java program 
    Serpent.gen_plains (see floppy #3). The magic plaintexts are extracted 
    from this file with grep and fed to the ecb_tbl test program. See the 
    Makefile for more details. 
 
  cbc_d_m.c 
  cbc_e_m.c 
  ecb_d_m.c 
  ecb_e_m.c 
    Monte Carlo (NB: with the above non-optimised reference code, these 
    take several hours each to run)
