For the published block cipher algorithm, the key design is an important part to a cryptographic system. Block ciphers used in network environment take more risks than ever before because of their initialization key’s distribution in internet openly. But key algorithm and block cipher algorithm combine model was ignored during a long period. If the key delay technology were used the speed of algorithm would be promoted and the chip’s area would be decreased with very low value. This article took an approach in block cipher’s key design against only known ciphertext attack. Furthermore, we discussed this design’s provable security according to information theory.
