TLDR
A new stream ciphering technique based on multiplicative polynomial inverses over Galois Field GF(73) is proposed, where a set of randomly generated key-bytes, between 1 and 15, is dynamically permuted and XORed with the identical number of message bytes.Abstract:
A new stream ciphering technique based on multiplicative polynomial inverses over Galois Field GF(73) is proposed, where a set of randomly generated key-bytes, between 1 and 15, is dynamically permuted and XORed with the identical number of message bytes. The output cipher is tested using NIST Statistical Test Suite and results are compared with that obtained by the well-known RC4 stream cipher. The new cipher is statistically random and observed to be better than RC4.read more

New systolic architectures for inversion and division in GF(2/sup m/)
Zhiyuan Yan,Dilip V. Sarwate +1 more
TL;DR: Two systolic architectures for inversion and division in GF(2/sup m/) based on a modified extended Euclidean algorithm are presented, one of which uses an adder or an (m+l)-bit ring counter inside each control cell, while the other distributes the ring counters into the computing cells, thereby reducing each control cells to just two gates.
