Security and mutual reliability are the crucial requirements of an ad hoc network as nodes are dependent upon each other for routing and forwarding their messages. Vehicular ad hoc networks (VANETs) are no exception and are always at the risk of impersonation attack. An authentication protocol protects the identity of network entities from being impersonated. Occasionally, they require re‐encryption technique which enables any other node to communicate on behalf of an unavailable node. The technology is used to provide backup in emergencies. We propose a secure authentication algorithm to efficiently re‐encrypt the messages using signcryption. For faster computation and routing, the authors have used shareable clouds in VANET groups. Security of the protocol is proved using Burrows–Abadi–Needham logic and validated by simulation tool automated validation of internet security protocols and applications.
