Parallel Processing Model of the Block Cipher
Yin Xin-chun · Mini-micro Systems · 2005
Taking AES as an example, parallel processing model of the block cipher is discussed. In the four parallel processing models of the block cipher except the ECB model, there exists iteration with feedback, which is an obstruction of parallel data processing. In this paper, three parallel cipher process models are presented. They can reach linear speed up without changing the cryptographic property of the original block cipher algorithm.
