【Abstract】 Based on usual knapsacks public key algorithm and DES cipher algorithm,a new chain block ci- pher algorithm is proposed in this article.According to the algorithm,a chain block cipher system is realized. The security strength,simpleness and speed of enciphering and diciphering about this system have been proved.It can make data true and can be applied to digital signatures.更多还原
