Secure Authentication for Vehicular Ad Hoc Network
Security is an important issue in ad hoc networks, especially fo r security sensitive applicat ions. This paper main ly focus the authentication based on the group signature for providing the security and privacy in vehicular ad hoc networks (VANET). In VANETs, g roup signature is widely used for vehicles to achieve unauthenticated vehicles. A group signature scheme allows members of a group to...
متن کاملImproved Access Control Mechanism in Vehicular Ad Hoc Networks
Access control of message is required when certain selected vehicles are granted access to information, instead of all vehicles within communication range. In these situations an access policy (consisting of attributes as road situation and vehicle type) is built into the vehicle and messages are encrypted using these access policies. Only valid vehicles possessing these attributes are able to ...
متن کاملImproving Performance of Opportunistic Routing Protocol using Fuzzy Logic for Vehicular Ad-hoc Networks in Highways
Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...
متن کاملQuick Message Authentication Protocol for Vehicular AD HOC Networks
Public Key Infrastructure (PKI) plays very important role in Vehicular Ad hoc Networks (VANETs). In this system; confirmation of received message can be done by checking the sender’s certificate is included in the Certificate Revocation Lists (CRLs), which means checking its revocation status, then, substantiating the sender’s certificate, and finally validating the sender’s signature. Since th...
متن کاملHasten Message Authentication Protocol for Vehicular Ad Hoc Networks
In Vehicular ad hoc network (VANET) vehicles communicates through wireless channels, so there will be variety of attacks. To secure vehicular ad hoc network, deployed Public Key Infrastructure (PKI), and to use Certificate Revocation List (CRL) for managing the revoked certificates. The authentication of received message can be performed by first check if the sender’s certificate is in current ...
