Abstract

The aim of this work is to investigate and define a dynamically adjustable security method, suitable especially for Wireless Sensor Networks (WSNs), usually composed by resource constrained devices. In order to support both the high level of security and the need for long lifetime of battery powered wireless devices, flexible means to adjust the level of security at runtime is needed. To this end, the paper proposes a solution, whose main component in the security between wireless sensors and the gateway is an Adaptive Security Manager (ASM), which can select the required level of security and inform the resource about it, based on the context. This makes it possible to support both high level of security and long lifetime of battery powered wireless devices when needed. Based on commands from the ASM, wireless sensors can select the suitable key from pre-shared keys (PSKs).
