1 Storin: a block cipher for digital signal processors
4 Storin is an 8-round SP network designed to play to the strengths of
5 digital signal processors.
9 configure A shell script to set up the Storin build
10 environment on your computer.
12 configure.in The m4 source code for configure.
14 aclocal.m4 Some m4 macros used by configure.in.
16 Makefile.in A skeleton Makefile for building Storin.
18 Makefile.am The Automake source for Makefile.in
20 bits.c, bits.h Bit-manipulation macros.
22 arith24.c, arith24.h Some simple 24-bit arithmetic.
24 matrix.c, matrix.h Matrix arithmetic over Z_{2^{24}}.
26 storin.c, storin.h The main cipher implementation.
28 sha.c, sha.h Implementation of SHA-1.
30 dsarand.c, dsarand.h SHA-1 based random number generator, suitable
31 for generating DSA parameters using the FIPS-180
34 fibrand.c, fibrand.h A fast non-secure Fibonacci generator with a
35 long period, a large state and good properties.
37 lcrand.c, lcrand.h A non-secure linear congruential generator with
38 good statistical properties used for seeding
41 storin-mktab.c A program for building Storin matrices. It uses
42 dsarand to provide confidence that `trap doors'
43 haven't been inserted in the matrix.

46 outputs test vectors in mLib/Catacomb format.
48 sym.c, sym.h An efficient extensible hashtable, used by
51 diffan.c A program to perform differential analysis of
52 the matrix multiplication.
54 sac.c A program to perform statistical testing of
55 three Storin rounds to ensure strict avalanche.
57 storin.ps A paper, in PostScript, defining the Storin
58 cipher and providing some preliminary analysis.
60 storin.tex The TeX source to the Storin paper.
62 storin.tests A file of test vectors useful for testing your
65 storin.debug A file showing a Storin key schedule and
66 encryption, with all intermediate values.
67 Useful when you're trying to produce your own
73 storin-debug Generates storin.debug.
75 storin-tests Generates storin.tests.
77 storin-mktab Generates the Storin matrix and its inverse,
80 diffan Performs a statistical differential analysis of
81 the matrix multiplication.
