| 9. | It ' s worth notice that , because the efficiency of public - key cipher is low , we introduce symmetric cipher , permutation code , and asymmetric cipher , rsa algorithm into the system to advance the efficiency of the whole system
值得指出的是，由于公钥密码体制效率较低，所以该系统采用对称密码算法和公钥密码算法相结合，采用排列码加密解密算法和rsa算法相结合，充分利用两者的优点，弥补其不足。 |
| 10. | A measure of the number of bits in a given key ; note that although increasing the key length gives added security , it s not appropriate to compare the lengths used with one cipher with those in another and , in general , that key lengths in symmetric ciphers do not equate directly with key lengths in asymmetric ciphers
给定密钥中位数的度量；注：虽然密钥长度越长，安全性越强，但将一个密码使用的长度与另一个的长度进行比较是不合适的，通常，对称密码中的密钥长度与非对称密码中的密钥长度不是直接相等的。 |
