Cryptography, Finite Fields, and AltiVec

[digdog]

by Bradley J. Lucier

Abstract.

The Tame Transformation Method (TTM) (http://www.usdsi.com) is a
public-key cryptosystem based on quadratic forms in finite fields.
The AltiVec instruction set in a PowerPC MPC7400 (G4) at 400 MHz
allows encryption with knowledge only of the public key at a rate
of over 18 million bits/second, and decoding, with knowledge of
the private key, at over 50 million bits/second. In this report
we explain how to exploit the AltiVec instruction set to speed
the basic operations in vector spaces over a finite field, where
the major computational resources of the TTM algorithm are needed.
