摘要
为了在有限资源的无线传感器网络上能安全进行群组通讯,同时考虑到组密钥管理必须满足前向安全性、后向安全性和完整性的安全需求,使用椭圆曲线密码体制的部分步骤和异或运算提出了一种安全有效的组密钥管理方案。与目前现有的群组密钥相比,方案不仅具有较好的效率,并且更适合于无线传感器网络。
To support secure group communications in resource constrained wireless sensor networks,and consider the security requirement of forward security,backward security and integrality that group key management must meet,a security and efficient group key management scheme which only uses elliptic curve eryptosystems and XOR is proposed.Compared with previous group key management schemes for wireless sensor networks,this scheme provides more efficiency and is more suitable for wireless sensor networks.
