无线传感器网络中一种基于公钥的密钥分配方案
Public key based key distribution scheme for wireless sensor networks
摘要
Abstract
Since key pre-distribution schemes based on symmetric key can not completely solve security problems of keys distribution in WSN, a new public key based key distribution scheme was proposed . In the scheme, public key set was generated by an initial public key set and a hash function in base station. Each sensor device was pre-distributed one public/private pair-wise key from public key set and a public key subset from the initial public keys set. Owing to uniqueness of private key, not only the communication security problems could be improved for WSN. But also the sensor-memory cost could be decreased. With the theorem of random-graph theory, the connectivity and scalability were illustrated. The results showed that the scheme was superior to the traditional key pre-distribution schemes.关键词
