Abstract
Due to the wide range of applications, Wireless Sensor Network(WSN) have recently attracted a lot of interest in the research community.WSN consist of large number of low-power sensor nodes, with limited processing, communication and storage resources. Due to limited resources of WSNs, it is challenging to incorporate basic security functions, such as authentication, privacy, confidentiality, availability and integrity etc. In order to protect the sensitive data and the sensor reading, secret keys should be used to encrypt the exchanged messages between communicating nodes. Because of high energy consumption and increased code storage requirement is needed by asymmetric cryptography such as RSA or ECC. Key management is one of the oldest areas in WSN security solution. This paper is devoted to the research on security efficiency for wireless sensor networks. The proposed scheme of IPC(Inter Process Communication) key management is based on the generation and distribution of the individual key, pair-wise key and the cluster head broadcast key. IPC have simulated and shows the performance for energy consumption with increasing number of neighbors, and time taken in individual key establishment with the number of nodes in the network. The security analysis shows that the scheme within this paper meets the unique security needs of the sensor networks.
