Pair-wise key establishment is a fundamental security service in sensor network and how to combine the characteristic of the sensor network is very important for improving the performance of pair-wise key. However, due to the resource constraints on sensor node, it is not feasible for sensor network to use traditional key management techniques such as public key and key distribution center (KDC). According to the character of sensor network grouping deployment, a general framework for establishing pair-wise keys between sensor nodes was developed by using bivariate polynomials and a novel Key Pre-distribution scheme was proposed based on k-GH (k-Grid Hypercube) model. The analysis and simulations show the new schemes have a number of nice properties, lower storage, communication overhead, better security performance. Hence, it is a high efficient and feasible scheme for establishing Pair-wise Keys on wireless sensor network.
