A protocol for secure and energy-aware reprogramming in WSN
Carlos F. Caloca, J. Antonio García‐Macías · 2009
Many protocols for reprogramming wireless sensor networks have been proposed, but most assume non-malicious nodes. Considering that this assumption is inadequate for many types of applications, we propose the protection of these networks by covering four security aspects: authentication, integrity, confidentiality and availability. Although similar proposals have already been presented, the problem we see with them is that while aiming for a complete and definitive solution they incur heavy resource consumption (e.g., energy). Since WSN are resource-constrained networks, we propose a pragmatic approach where we try to balance these two opposing design elements: security and resource consumption. We evaluate our proposal to show that such balance can be achieved, and state that this approach is more convenient in the real world than a "definitive" security solution that takes a heavy toll on resources.
