The Snapshield software engine, which utilizes Snapshield's cryptography library for the TMS320C54X, TMS320C55x and the TMS320C62x DSPs from Texas Instruments, contains algorithms for symmetric block cyphers, one-way hash functions, public key encryption and digital signature. The demonstration is located in the Texas Instruments booth on the exhibition floor.

Treating a block of plain text as a whole, Snapshield uses symmetric block cyphers to generate a cipher text of equal length, with the same algorithm and key used at both the encrypting and decrypting ends. Snapshield has the ability to employ Triple DES (3DES), which achieves a higher level of security by encrypting the data three times using DES with three different, unrelated keys. In addition, the software engine is fully capable of employing other advanced cyphers such as AES, which employs a variable key length of up to 256 bits. According to Snapshield, the company's software engine and cryptographic library can transform these and other standards into highly efficient code for use with TI's fixed-point DSP family.
