Abstract
AbstractThe Web PKI plays a more and more important role in network security, as nowadays TLS and HTTPS are being widely adopted. The most significant recent advances in the Web PKI include certificate transparency and push-based revocation, which improve the trustworthiness and performance of TLS and HTTPS, respectively. Meanwhile, SCMS is a specialized PKI system designed for V2V communications. In this paper, we analyze the design principles of certificate transparency and push-based revocation, study the similar requirements in V2V communications, and then summarize the technical challenges to integrate certificate transparency and push-based certificate revocation into SCMS. From the experiences and lessons in the Web PKI, we do believe that the current designs of SCMS are still not completely ready to be deployed in the real world.KeywordsPublic key infrastructure (PKI)Transport layer security (TLS)CertificateSecurity credential management system (SCMS)Trust managementVehicle-to-Vehicle (V2V) communication
