Towards Scalable Certificate Status Validation in Mobile Ad Hoc Networks

Certificate validation is an important operation in the PKI-based security systems and its overheads have direct impact on the performance of PKI system. ADOPT is an effective certificate validation protocol that tries to tune the OCSP protocol to multihop wireless networks by using caching techniques. In this paper, the authors present a protocol called BP-ADOPT to decrease the overheads of the ADOPT-based certificate validations in mobile ad hoc networks. This solution also increases the security of ADOPT protocol by making it more resilient against the DoS attacks and improves its scalability and throughput. Finally, the authors present an analysis of our solution and ADOPT protocol in mobile ad hoc networks.
