A Novel Encryption Algorithm of Replace Key Matrix
Ye Feng · Nanjing Hangkong Hangtian Daxue xuebao · 2005
A novel encryption algorithm based on the replace key matrix(RKM) is presented.RKM cryptosystem is a block cipher operated on a 128 bits or a 256 bits block of the plaintext.The eneryption algorithm for RKM is based on a 16×16 key matrix,and the ciphertext is deduced by the byte of RKM converted from the plaintext.The horizontal and vertical eigenvectors,the domino affect are introduced in RKM.The algorithm design and the security analysis are presented and the security of RKM is improved.
