| 摘 要： | 针对敏感信息的安全问题,设计一种基于顺序序列的概率多变量公钥密码体制,其中新明文中的明文与扰动信息先后顺序保持不变,但新明文中各项位置随机.解密时,需要相同的两组新明文进行对比,找出二者各项的对应关系,即可得到明文.该公钥密码体制具有较好的随机性,由于基于一次一密思想,因此安全性较高.

| Abstract: | Aiming at the problem of the security of sensitive information, we designed a probabilistic multivariate public key cryptosystem based on ordered sequences. The sequence of plaintext and disturbance information remained unchanged in the new plaintext. However, the position of each item of the new plaintext was random. In the process of decryption, we needed the same two sets of new plaintext for comparison, and found out the corresponding relation in each item, in which the original plaintext could be obtained. The public key cryptosystem based on one timepad has good randomness, so it has higher safety. |
