| 摘 要： | 无线传感器网络节点的计算、存储和通信能力都十分有限,通常被认为不适合使用公钥密码学技术。然而,近年来的许多研究成果表明,一些经过优化的公钥算法是可以为无线传感器网络提供更加有力的安全保障的。该文基于身份的密码系统进一步简化了传统公钥系统,根据无线传感器网络自身的特点,对现有的基于身份的签名算法的安全模型进行改进,并在此基础上提出了新的签名算法,同时也给出了安全证明。现有算法的存储需求与被签名信息长度成正比,而新算法存储需求为常量,因此更加适合在无线传感器网络中的使用。

| Abstract: | The nodes of wireless sensor network are very limited in its processing power, storage capacity and communications capability, so it is usually to be considered unsuitable for the use of public key cryptography technology. However, in recent years many research results indicated that some optimized public-key algorithm can provide much more security for wireless sensor networks (WSN). The identity-based public system simplifies the certificates management which is cumbersome in certificate based public key ... |
