Signal Display Systems has developed encryption software based on a new discovery in chaos theory that expands fractal-dimensions with a simple algorithm (see details - example source code, white paper). It can be used to encrypt any type of document quickly and simply regardless of data format or it can be used to improve the signal-to-noise ratio of wireless links. A free-demo version is available for download (Download Demo Version) as a 15-day trial and the full-version with no time limitations can be ordered securely online (secure order form).

The tool generates the key used to encrypt or decrypt data using nonlinear differential equations. Before it can begin, the user must supply four, non-zero numbers (256 bits total) in the range of -0.2 and +0.2. The only information that need be shared between the one who encrypts the data and the one who decrypts it are the four numbers that act as keys in encrypting the data.

Usage example:

to encrypt:

encrypt data_file.txt result_file.enc 0.15 0.16 -0.17 0.19

to decrypt:

decrypt result_file.enc clear_file.txt 0.15 0.16 –0.17 0.19

Arguments:

1) Name of file to encrypt/decrypt

2) Name of output file

3) First real number value for key generation

4) Second real number value for key generation

5) Third real number value for key generation

6) Fourth real number value for key generation

Real number values are subject to the following conditions:

non-zero in the range [-0.20 and 0.20]

The user will be prompted for real number values if not specified on the command line.

The demo version uses only two real-number inputs as keys (limited to 128 bits). Also, the demo can only be used on small files (32M or less). Our licensed, fully capable version has no such limitations (can do file sizes up to 400 MB) and uses our exclusive feedback algorithm to randomize key length.

We believe the non-linear nature of chaos theory offers excellent encryption due to the chaotic nature of the data in the key sequence generated and the indeterminable key length. Also, because we derived our algorithm from a working model that is not well publicized and uses 256 bits total, we offer more security than other encryption programs. Chaocrypt recently passed the NIST test for randomness (DFT, Frequency, Cumulative Sums) with a 6x passing score. Chaotic sequences have also been shown to improve the SNR of wireless links (i.e., fewer dropped calls) over standard Gold or PN encoding.
