Clustering-Based Merkle Hash Tree Entity Authentication Scheme for Wireless Sensor Network
Xianwei Zhou · Chuangan jishu xuebao · 2007
Wireless sensor network is characteristic of limited energy, computation and memory. Public key algorithm and digital signature consume high energy. A novel entity authentication scheme based on Merkle hash tree for Clustering-Based sensor network (CMAS) is proposed to solve such problems. This method using the concept of Merkle hash tree may obtain an effective safe authentication strategy. Combining the network clustering technology, this scheme has more practical use in large-scale network. Moreover, symmetrical key algorithm is used to avoid large computation, which effectively reduces the authentication delay, increases the network lifetime and enhances the security of the network. Simulation results show that the scheme is valid.
