Abstract: currently no proposed work addresses all of the requirements for message and entity authentication in VANET system. This paper focuses on the authentication scheme which is based on number theory as it plays a vital role in network system communication. In this paper, we discuss a novel, robust and efficient authentication protocol which is based on number theory principles involving LE using novel key sharing scheme employing probabilistic random keys which allows an OBU to update its compromised keys. VANET is a type of Ad hoc network in which vehicles act as nodes for exchanging all type of information. Here, we experiment the NTBS with LE for obtaining Authentication mechanism for transferring and receiving resources of network. In VANETS the primary and crucial components of security are recognized as node authentication, message integrity, data availability, non-repudiation, and data confidentiality. From above node authentication mechanism is crucial challenge in VANET. So, we concentrate and invent a authentication protocol.
