Abstract :
A novel generation key scheme based on DNA is proposed. By using a key expansion matrix, the scheme improves the independence and the strict avalanche of the key. Although it increases computation amount because of using the matrix operation, the random number can be generated by the DNA sequence directly and the speed of the computation is greatly improved. Therefore, the new scheme has wide application in the field of the block cipher, data signature, identity authentication, et al.
