Confidentiality and authenticity are two important security services required for almost every WSN application. However, small memory, weak processor and limited battery power of the sensor nodes are the major obstacles to implement traditional security primitives in them. Owing to both, the requirement as well as the obstacles, this paper proposes a LIghtweight Security Algorithm (LISA) tailored to implement in resource restrained sensor nodes. The novelty of this scheme is that it achieves both, confidentiality and authenticity of data, without using traditional encryption algorithm.
