Vehicular communication and networkin g for intelli g ent transportation systems are emer g in g concept which allows forwardin g of traffic information. Road traffic crashes are one of the lar g est problems bein g faced. V ANET's are self or g anized networks in which vehicles communicate with each other without the presence of any priori infrastructure. The proposed scheme aims to develop applications related to vehicular safety by providin g information related to road and traffic. Vehicles share the surroundin g information with each other. In this paper we include the development of self-mana g ed V ANET's that does not require the deployment of infrastructure with detection and warnin g about abnormal traffic condition by the secure routin g of vehicles. Initially the vehicle re g istration is done usin g the public key g enerated by RSA al g orithm. Then the verification of the vehicles is done usin g Zero Knowled g e Proof al g orithm and the attackers are also detected and eliminated from the network.

“…During the authentication procedure, the prover, denoted A, must answer to a number of challenges issued by the verifier, denoted B. The admission control included in the authentication proposal described below uses the general scheme of ZKP described in [2] based on the graph isomorphism problem, for the particular case of the Hamiltonian Cycle Problem (HCP), which involves the determination of whether a cycle that visits each node exactly once exists in a graph.…”

This paper proposes a new solution for the practical, fast and secure deployment of vehicular networks. Its main contribution is a self-managed authentication method that does not require the participation of any certification authority because the nodes themselves certify the validity of the public-keys of the nodes they trust, and issue the corresponding certificates that are saved in local key stores according to an algorithm here proposed. In addition, the new node authentication method includes a cryptographic protocol that each node can use to convince another node about the possession of certain secret without revealing anything about it. Thanks to all these tools, cooperation among involved vehicles can be used to detect and warn about abnormal traffic conditions. One of the most interesting aspects of the proposal is that the required devices can be simple existing mobile devices equipped with wireless connection. This work includes a performance analysis of a simulation of the proposed algorithms and the obtained results are promising.

“…Until now very few publications have mentioned the proposal of authentication systems for ad-hoc networks using ZKPs [6] [2] [13], and none of them has dealt with the related problem of topology changes in the network. A recent ZKP-based hierarchical proposal for MANETs related with the one proposed here was described in [4], where two different security levels were defined through the use of a hard-on-average graph problem, and no topology changes were considered.…”

This work proposes a new global authentication system for Mobile Ad-hoc Networks. The component algorithms are designed in a self-organizing way so that most needs of this sort of networks are covered. In particular, characteristics such as adaptation to the varying topology of the network, open availability of broadcast transmissions, and strong access control have received special attention when defining the new scheme. The described protocol is based on the cryptographic paradigm of Zero-Knowledge Proofs. In this paper the design is thought for the Hamiltonian Cycle Problem, but it might be easily adapted to other NP-complete graph problems.
