Abstract.
Sensor networks offer the advantages of simple and low-resource
communication. Nevertheless, security is of particular importance in many
cases such as when sensitive data is communicated or tamper-resistance is
required. Updating the security keys is one of the key points in security,
which restrict the amount of data that may be exposed when a key is
compromised. In this paper, we propose novel key update methods, and
benefiting from stochastic model checking we propose a novel method for
determining optimal key update strategies for custom network scenarios. We
also present a case study where an application in commercial building
automation is considered.
