摘要
从密钥存储量负载、通信负载和节点能耗等方面,对三个具有代表性的密钥建立协议SPINS、Random Key Scheme和PeerSiz进行了能耗测试和分析,结果表明:尽管基于对称密码体制的密钥建立协议的能耗远小于基于公钥体制的协议,但是如果选择部署了合适的密码算法,如ECC-160,基于公钥体制的密钥建立协议也能够较好地适应无线传感器网络环境。
Comparisons are made for the memory overhead, communication overhead and node's energy consumption of the three typical protocols: SPINS, Random Key Scheme and PeerSiz. The results indicate that though the energy consumption of symmetric-key protocol is smaller, with better scalability and security, the asymmetric-key based protocol is quite acceptable with proper algorithm such as ECC-160.
