摘要：

无线传感器网络节点的通信和计算能力非常有限,使得传统的公钥加密算法无法有效应用,为此提出了一种安全的轻量级的加密算法.基于身份的密码系统简化了基于证书的密码系统繁琐的密钥管理过程,根据无线传感器网络自身的特点,对现有的基于身份的加密算法安全模型进行改进,提出了一个新的安全模型,并在此基础上提出了一种在标准模式下可证明安全的基于身份的加密算法.与现有的基于身份的加密算法相比,提出的加密算法存储需求更小、计算量更少,更加适合于无线传感器网络.
Abstract:

As the key technology of pervasive computing, wireless sensor network’s (WSN’s) node is very limited in its energy, processing power, storage capacity and communication capability, so it’s usually  considered unsuitable for the use of public key encryption technology. But the identity-based encryption (IBE) makes it possible to use public key encryption technology in WSN. IBE system simplifies the certificate management which is cumbersome in the certificate-based public key system. According to the features of WSN, the security model of IBE system was modified and an IBE system was proposed, which was proved secure in the new security model without random oracle. Comparison with previous IBE system showed that the proposed system needs less storage and is more efficient. So the proposed system is more suitable for WSN.
