* imported implementation of MOUSTIQUE (test suite still does not 
support self-synchronizing stream ciphers, though). 

Reference code for Moustique

Design by Joan Daemen and Paris Kitsos

This includes the following files:
ecrypt-Moustique_cipher.c:  contains reference code
ecrypt-ssyn.h:  header file of reference code
main.c:                     contains program to generate testvalues
Moustique_testvalues.txt:           contains testvalues
Moustique_testval_in.txt:             contains input file to generate testvalues
readme.txt:                 this file


On the reference code

Moustique has an internal state and this is kept in a structure ECRYPT_ctx specified in the file "ecrypt-ssyn.h"
When a new instance of this structure is created, one shall perform an initialization by calling the function "void init_ctx(ECRYPT_ctx *s)".

On the representation of testvalues

Moustique operates on single bits. Still, we use a byte-oriented notation in these files. The bit that appears first is the bit with the lowest (time)-index. 
- keys have a length of 12 bytes,
- IV values have a length of 13 bytes,
- plaintext and ciphertext both have a length of 16 bytes.

On the range of testvalues

The file "testvalues.txt" contains:
- 64 ciphertext values corresponding to 4 plaintext values encrypted using 4 different key values and using 4 different IV values.
- 64 plaintext values corresponding to 4 ciphertext values encrypted using 4 different key values and using 4 different IV values.
The contents of this file can be regenerated using the main program in "main.c" with as input the file "testval_in.txt".

The key values:
00 00 00 00 00 00 00 00 00 00 00 00
FF FF FF FF FF FF FF FF FF FF FF FF
01 23 45 67 89 AB CD EF 01 23 45 67
