摘要
S-MAC协议是在802.11MAC协议基础上提出的传感器网络MAC协议。首先简要介绍了无线传感器网络及其主要特点和问题,接着介绍了无线传感器网络的安全需求,然后提出了安全的SSMAC协议,其中使用公钥加密算法NTRU来实现SSMAC协议的数字签名.最后采用NS-2平台对其进行仿真,并进行了性能和安全性的分析.仿真和分析结果表明,SSMAC能保证通信包的数据完整性,身份真实性和抗否认。与RSA公钥算法相比,NTRU加解密速度更快,适合于无线传感器网络。
S-MAC protocol was sensor protocol proposed on basis of 802.11MAC protocol. In this paper, at first the main characters and problems of wireless sensor networks were introduced. Then the security demands of wireless sensor network were introduced, And a secure SSMAC protocol was proposed. In this protocol, NTRU was used to realize Digital Signature, At last NS-2 platform was adopted to simulate it and make performance and security analysis. The simulating and analysis resuits showed that SSMAC was able to assure data integrity, identity authenticity and anti-deny of communicating packets. NTRU speed of encryption and decryption was faster than RSA. It was fit for wireless sensor networks.
