Feasibility of TEA in wireless sensor networks

Due to resource constrained environments under which the wireless sensor networks operate, the security algorithms should be so designed to be used in WSNs, as a result the optimum resources and less energy consumption. Security to sensor nodes is a particularly challenging task. The literature proposed extensions tiny encryption algorithm and discussed their countermeasures. The literature survey proposed a brief discussion on black hole attacks which occur when an adversary captures and re-programs a set of nodes in the network to block/drop the packets and generates wrong/false messages instead of forwarding true information towards the base station. This paper briefly discusses about security mechanisms and feasibility of Tiny Encryption Algorithm on sensor nodes for authentication and encryption of information. This paper proposes feasibility for wireless sensor network by introducing a lightweight, fast, efficient Tiny Encryption Algorithm based on security solution against black hole attack in wireless sensor networks (WSNs).
