The aim of the study is to analyze the application of the Modulo Key Pre-Distribution (MKPD) protocol which is developed for Wireless sensor network (WSN). WSN is a collection of a large number of sensor nodes with limited resources. Bootstrapping secure communication among sensor nodes deployed in hostile environment is an important and challenging problem. An adversary may physically capture some sensors to compromise their stored sensitive data and secret keys which are used to attain confidentiality of the sensitive data. A common approach to solve problem is to use a key pre-distribution scheme in which each sensor node is assigned a subset of keys (key chain), selected from key pool prior to deployment. The keys are carefully selected that have high key sharing probability and resistance against node capture. We use deterministic key distribution scheme based on modulo function to establish the pair-wise keys among the sensor nodes. This study focuses on the application of this Modulo Key Pre-Distribution (MKPD) protocol to a group communication. It provides good key connectivity between the sensor nodes belongs to that group. And also opportunity available to increase the scalability in MKPD protocol by complementary design is also explained.
