Study on group key agreement using two-dimensional array in sensor network environment

Abstract

These days, with the implementation of ubiquitous computing concept, sensor networks that collect analyze and process information of things and environment through sensors have become a huge interest as the technology that would realize this concept. However, sensor network technology has wireless communication infrastructure as its foundation and fundamentally has security weakness with limitations on low computing capacity, power supply and low budget. The core of group telecommunications between sensor network sensor nodes is the group key management. Managing group key requires appreciating group key security and management mechanism efficiency. This paper takes the characteristics of sensor network into consideration and not only increases the group key agreement efficiency through Two-dimension array key set distribution and not the existing group key method to satisfy both the network function and security but also protects information between each nodes thereby enhancing the sense of security. © 2011 Springer-Verlag.
