A review on desirable measures for good Key Pre-distribution Scheme in wireless sensor network

摘要

A Key Pre-distribution Scheme for a sensor network is an essential part for the security of information collected by a sensor node. A set of keys are required to be pre-distributed prior to deployment of the sensor nodes. These keys are used to encrypt the collected sensitive data from a targeted area. Key Pre-distribution schemes (KPS) are methods for allocating symmetric cryptographic keys to sensor nodes in a network. As sensor nodes are of less storage capacity and low computation power leads to a trade-off between key storage, connectivity and resilience, where resilience is the measure of the network's ability to withstand damage from an adversary, the limited storage and computational capacities of the nodes are an important consideration in the design of a key pre-distribution scheme. Here we discuss different desirable measures for a good key pre-distribution scheme for a wireless sensor network.
