| Summary: | Vehicular ad hoc network (VANET) has attracted much attention from academia and industries in recent years.
Security remains the major concern for VANET application due
to innate time constrains. Researchers have proposed a number of solutions to counter such attacks and also to improve certain aspects of security i.e. authentication, privacy, non-repudiation etc. Some of the solutions are based on group formation concept but most of these solutions work under the simple assumption of an existent group formation method. Furthermore the role of a group leader is expected to be short lived and thus a question
mark in the context of highly dynamic VANET topology.
Disseminating message in a secure manner over relevant
geographical area is another challenge for VANET. In this paper we propose two schemes one for efficient group formation that improves life time of a group leader role. We also propose hybrid (symmetric/asymmetric) message dissemination scheme for faster and secure communication. Both these schemes are the extensionof our previously proposed security framework. |
