| 摘 要： | 通过将分组密码算法和序列密码算法的优点相结合，给出一个易于软件和硬件实现的对称钥
算法方案（SCB算法）。从对一个数据块进行加密来看，SCB算法属于重复迭代型分组加密。
然而，从攻击者角度来看，如果不穷举密钥，他将面对一个具有一次一密特征的密码算法。

| 关 键 词： | 数据加密 对称钥加密算法 序列与分组密码杂交 一次一密 |

| Abstract: | 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. |

| Keywords: | data encryption symmetric key encryption algorithm the crossbreed of block and stream ciphers one-time-pad |
