Hybrid and Lightweight Cryptography for Wireless Sensor Network
一种混合轻量型无线传感器网络公钥密码方案

Combined identity-based system with the idea of lite-CA(Certificate Authority),a scheme of identity-based and lightweight CA-based cryptography for wireless sensor network was proposed.The scheme not only avoids the drawback of private key escrow in the identity-based system,but also gains the advantage of simplifying complication of producing and verifying public key in traditional certificate-based CA system.Analysis shows that the scheme equips with characteristics of lite-producing public key,lite-verifying public key,certificate less,and high security which can defense some attacks easily carrying into wireless environment.It is applicable to be used in wireless network to gain data confidentiality,integrity,and non-refutation.
