| 摘 要： | 为提高无线传感器网络机密通信的有效性,提出了基于SP结构的WSN单字节密钥方案。采用shifter（移位）,permutation（置换）以及异或操作对明文进行加密,然后再对密文采用移位、置换和异或组合操作进行解密。分析了移位、置换和异或操作原理,给出了机密算法。明文通过SP结构操作加密得到的密文能够同样通过SP结构解密。分析表明,单字节的SP结构的加密与解密可以用于WSN的机密通信。

| Abstract: | In order to increase the efficiency for confidential communication in wireless sensor networks,the SP operation was proposed to process single byte in cipher algorithm.The algorithm utilizes the operation of shift,permutation and exclusive OR to encrypt plain texts,and to decrypt cipher text in the same operation method.In the paper,the principle of the shift,permutation and exclusive OR operation were introduced,then the cipher algorithm was brought forward.The conclusion is the confidential communication in wireless sensor network based on SP operation is right and feasible. |
