摘要
通过给出一个易于软件和硬件实现的对称钥密码算法(SCB算法)实例,探讨了密码算法设计中将分组密码算法的优点和序列密码算法的优点相结合的可行性,论述了这类算法在安全和效率方面的根本优势.这类拥有分组密码算法和序列密码算法双重性征的对称钥密码算法,具备了较好的抗攻击性能,因此,会有很好的应用前景.
By presenting a concrete symmetric key cipher scheme SCB, which is easily implemented in both software and hardware, the possibility of mixing both the advantages of block and stream ciphers in one encryption scheme is discussed. The essential superiorities on security and efficiency are stated. Such cipher schemes which have both the features of block and stream ciphers have good properties on anti-attacks. And thus, it will have a good future on the application.
