On the Impact of DoS Attacks on Secure Service Discovery

Service discovery, an essential building block of nomadic and ubiquitous computing applications, needs to be secured to be effectively deployed. Centralized and decentralized approaches have been proposed to this end. This paper analyzes the application layer secure matching function using a Markovian performance model in order to analyze the effects of DoS attacks in centralized and decentralized service discovery systems and to assess anti-clogging mechanisms as a protection against such attacks. This study highlights the determinant parameters that should be evaluated for ensuring a scalable and secure service discovery deployment.
