Storin: a block cipher for digital signal processors
Storin is an 8-round SP network designed to play to the strengths of
digital signal processors.
Files included:
configure A shell script to set up the Storin build
environment on your computer.
configure.in The m4 source code for configure.
aclocal.m4 Some m4 macros used by configure.in.
Makefile.in A skeleton Makefile for building Storin.
Makefile.am The Automake source for Makefile.in
bits.c, bits.h Bit-manipulation macros.
arith24.c, arith24.h Some simple 24-bit arithmetic.
matrix.c, matrix.h Matrix arithmetic over Z_{2^{24}}.
storin.c, storin.h The main cipher implementation.
sha.c, sha.h Implementation of SHA-1.
dsarand.c, dsarand.h SHA-1 based random number generator, suitable
for generating DSA parameters using the FIPS-180
algorithm.
fibrand.c, fibrand.h A fast non-secure Fibonacci generator with a
long period, a large state and good properties.
lcrand.c, lcrand.h A non-secure linear congruential generator with
good statistical properties used for seeding
fibrand.
storin-mktab.c A program for building Storin matrices. It uses
dsarand to provide confidence that `trap doors'
haven't been inserted in the matrix.
storin-tests.c A program for making Storin test vectors. It
outputs test vectors in mLib/Catacomb format.
sym.c, sym.h An efficient extensible hashtable, used by
diffan.
diffan.c A program to perform differential analysis of
the matrix multiplication.
sac.c A program to perform statistical testing of
three Storin rounds to ensure strict avalanche.
storin.ps A paper, in PostScript, defining the Storin
cipher and providing some preliminary analysis.
storin.tex The TeX source to the Storin paper.
storin.tests A file of test vectors useful for testing your
implementation.
storin.debug A file showing a Storin key schedule and
encryption, with all intermediate values.
Useful when you're trying to produce your own
implementation.
Programs built:
storin-debug Generates storin.debug.
storin-tests Generates storin.tests.
storin-mktab Generates the Storin matrix and its inverse,
given a seed string.
diffan Performs a statistical differential analysis of
the matrix multiplication.
sac Performs statistical testing of Storin for
strict avalanche.
