摘要: 为了解决无线传感器网络中所传数据的机密性和完整性问题,本文提出一种高效的无线传感器交叉加密认证方案。该方案基于对称密钥密码系统,网络中的节点只和其2跳以内的节点共享密钥,传输中的密文始终只加密2层,从而降低存储密钥的空间,减少加、解密时的计算量。此外,方案在加密时引入带投票技术的认证功能,从而在保证数据机密性和完整性的同时大大降低消息丢失的概率。

Abstract: In order to solve the problem of the confidentiality and integrity of the data on wireless sensor network (WSN), an efficient interleaved encryption and authenticated scheme on wireless sensor networks is put forward in the paper. The scheme is based on symmetric key encryption. The nodes on the networks only shared keys with those nodes in tow hops, and the cipher is always encrypted two layers. This way, the storage space of keys is decreased, and the calculated amount of encryption and decryption is reduced. Beyond that, the function with voting technology certification is introduced in the scheme, which can reduce the probability of message loss significantly under the premise of the integrity and confidentiality.
