Abstract
Advancements in wireless sensor networks (WSNs) technologies have enabled their introduction in various application fields. A large number of these applications use sensitive data that require securing algorithms. In this paper, we present a comprehensive survey on the most commonly used security techniques in wireless sensor networks. In this survey, we also present the different implementations on numerous platforms used to realize these security algorithms with special attention to power consumption. Based upon our findings, we propose the main characteristics and parts of a new solution to realize a low power wireless sensor node with high level of security.
