The document proposes an efficient authentication scheme for vehicular ad hoc networks (VANETs) that addresses the limitations of existing signature methods based on trusted authorities, particularly the need for certificate distribution and revocation lists. By integrating self-healing key distribution and certificateless signatures in a semi-trusted authority environment, the new scheme eliminates the necessity for vehicles to store large CRLs, thus saving storage and improving communication efficiency. The scheme's realism is enhanced by its design, which aligns better with practical deployment needs in intelligent transportation systems.
An Efficient Authentication Scheme Based on Semi-Trusted Authority in VANETs
- 1. An Efficient Authentication Scheme Based on Semi-Trusted Authority in VANETs ABSTRACT: With the development of intelligent transportation systems, vehicular ad hoc networks (VANETs) are widely used in safety driving, and so on. However, existing signature schemes, such as pseudonym- and group-based schemes, have certain problems, such as the need for a certificate distribution and certificate revocation lists (CRLs). With such schemes, the vehicle needs to store a valid certificate generated by the management center. Simultaneously, the receiver needs to check the CRLs prior to message authentication. CRLs require large amounts of storage space and computational and communication resources. In addition, many such schemes are built on a trusted authority and do not meet real world needs. Thus, we propose an efficient authentication scheme based on semi-trusted authority in VANETs. In this scheme, we combine the self-healing key distribution method with a certificateless signature in a semitrusted authority environment, such that the receivers do not require to query the CRLs. Therefore, the vehicles do not have to store the CRLs, thereby saving storage space and communication resources. This also reduces the computational costs and improves the efficiency of the message authentication. Since the proposed scheme is built on a semitrusted authority, it is a more realistic approach.
