The Key Predistribution Mechanism for Wireless Sensor Networks

Abstract

For symmetric key-based key distribution techniques will not completely solve the security problem of key distribution in wireless sensor networks, a public key with certificate-based key pre-distribution scheme, the base station using a series of original public key and a single collection to the hash function to produce a public key, and for each node were randomly assigned to a subset of public and private key and public key set. Private key only, the program can not only improve the safety performance of the network, but also improve the storage overhead of the network. The program compared with the traditional key pre-distribution scheme, both to ensure the security of the network, both network and node resources are limited practical under the premise of constant connectivity, network security and network scalability margin to improve.
