As wireless sensor networks continue to grow in usage for distinct applications. Storage (memory) requirement and security are major problems for these resource limited networks. This paper present a novel and an efficient key establishment and management scheme for WSNs, named Random Initial and Master Key (RIMK). The authors showed that their proposed technique, manages keys randomly with less storage (i.e. only two keys), less communication and computation overhead compared to existing Localized Encryption and Authentication Protocol (LEAP), in which every node uses four different keys in a static pattern and occupy greater storage space, which increases overhead and complexity in the network. Simulation results show that RIMK is more efficient and robust than LEAP.
