A Heterogeneous Cross-Domain Conditional Privacy Protection Ring Signcryption Scheme for V2I Communication
The vehicles-to-infrastructure(V2I)communication is an important component of vehicle self-organizing networks.Ensuring secure transmission of messages in V2I has always been a focus of research,and various conditional privacy protection schemes suitable for V2I communication have been proposed in recent years.However,in most existing ring signcryption-based schemes,the common assumption is that both the sender and receiver must be within the same cryptographic system and use the same system parameters within the same domain.With the complexity of communication scenarios,this assumption has limitations,and most signcryption-based schemes fail to meet the known temporary session key security.To address these issues,we proposed a heterogeneous cross-domain conditional privacy protection ring signcryption scheme for V2I communication.Our scheme enabled cross-domain communication between vehicles in certificateless cryptography(CLC)and infrastructure in Public Key Infrastructure(PKI).In the Random Oracle Model(ROM),our scheme satisfied confidentiality and unforgeability through rigorous security proofs.Compared with four schemes that provide similar functions,our scheme has the lowest computing cost and tracking cost.
