Key Update Strategies for Wireless Sensor Networks
Keywords:
Key management, security, sensor networks, verification.Abstract
Wireless sensor networks offer the advantages of
simple and low-resource communication. Challenged by this simplicity and low-resources, security is of particular importance in many cases such as transmission of sensitive data or strict requirements of tamper-resistance. Updating the security keys is one of the essential points in security, which restrict the amount of data that may be exposed when a key is compromised. In this paper, we investigate key update methods
that may be used in wireless sensor networks, and benefiting from stochastic model checking we derive characteristics of these methods in security perspective.
