Ensuring communications security in Wireless Sensor Networks (WSNs) indeed iscritical; due to the criticality of the resources in the sensor nodes as wellas due to their ubiquitous and pervasive deployment, with varying attributesand degrees of security required. The proliferation of the next generationsensor nodes, has not solved this problem, because of the greater emphasis onlow-cost deployment. In addition, the WSNs use data-centric multi-hopcommunication that in turn, necessitates the security support to be devised atthe link layer (increasing the cost of security related operations), instead ofbeing at the application layer, as in general networks. Therefore, anenergy-efficient link layer security framework is necessitated. There do existsa number of link layer security architectures that offer some combinations ofthe security attributes desired by different WSN applications. However, as weshow in this paper, none of them is responsive to the actual security demandsof the applications. Therefore, we believe that there is a need forinvestigating the feasibility of a configurable software-based link layersecurity architecture wherein an application can be compiled flexibly, withrespect to its actual security demands. In this paper, we analyze, propose andexperiment with the basic design of such configurable link layer securityarchitecture for WSNs. We also experimentally evaluate various aspects relatedto our scheme viz. configurable block ciphers, configurable block cipher modesof operations, configurable MAC sizes and configurable replay protection. Thearchitecture proposed is aimed to offer the optimal level of security at theminimal overhead, thus saving the precious resources in the WSNs.
