“…To avoid this problem, VANETs have to furnish non-repudiation of the messages, using asymmetric cryptography based on two keys [23-25-38]. As known, VANETs access infrastructure via RSUs or Hot Spots, and the vehicles are registered with CA, which is suitable for asymmetric cryptography [39]. The CA guarantees the non-repudiation of messages because it manages the identities and credentials of all nodes registered with it.…”

Vehicular Ad Hoc Networks (VANETs) are based on network technology where cars act as mobile nodes to form a communication network. In VANETs, routing protocols have a significance regarding the overall network performance since they determine the way of sending and receiving packets between mobile nodes. Most of the protocols proposed for VANETs are adapted from Mobile ad hoc networks (MANETs) routing protocols. However, due to the specific characteristics of VANETs, especially high mobility, and dynamic topology, the routing protocols in ad hoc networks do not adapt immediately to VANETs. Therefore, secure routing of Vehicular ad hoc networks (VANETs) against attacks, which are of various types, is still a challenging issue. This paper is going to present a synthesis of the most relevant protocols that have addressed the secure routing issue in VANETs. It also establishes a comparison regarding the offered features and the studied performance aspects through which it is notified that a security mechanism depends not only on the level of efficiency but also on the network constraints.

Vehicular Ad-hoc networks (VANETs) require trusted vehicles to vehicles communication. VANET is multidimensional network in which the vehicles continuously change their locations. Secure routing is imperative during the routing process to incorporate mutual trust between these nodes. Sometimes, the malicious node broadcast the bogus information among other nodes. Establishing trust is a challenge while one or more malicious nodes attempt to disrupt route discovery or data transmission in the network. A lot of research has been carried out for secure routing process with trust-based approaches. In this paper, we present survey of various mechanisms to improve different ad-hoc routing protocols for secure routing process by enhancing the trust among different nodes in VANETs.

Cluster computing in ad hoc network draws special attention among the research community as it mandates the usage of single bandwidth for many receivers associated with the group/cluster. Ad hoc network operational environment has incited the adoption of cluster computing as it innately assists its formation. Cluster computing in ad hoc network has undergone a paradigm shift in the deployment of community centric applications like multiparty video conferencing, multiplayer online video games, online software patch update and online auction etc. Clusters in ad hoc network collaborate with each other through trust based routing using group key GK. Cluster members in the group are in possession of three keys namely a private key for decryption, public key for encryption for one-one communication between the group members and the local group key (LGK) for corresponding with the group head and broadcasting the message to other peers.Group head handshakes with other group members using the established and recommended LGK. The global group key (G 2 K) possessed by each group head aids in inter group communication for encrypting the group message and the LGK for decrypting the enciphered group message. The inter collaboration between the clusters necessitates strong association among the group keys namely LGK and G 2 K triggering upscale/upward group communication through efficient group key climbing and chaining mechanism. The cluster key pool viz. the group key associated with the group head and the group member's key are established during the set up and connection phase that sustains until the clusters encounters one of these special conditions. Group head drifting from the cluster, a node joining/leaving to/from a cluster (forward and backward secrecy), compromised keys, and periodical key updates induces a rekey mechanism for the cluster. The storage, computation and communication complexity involved in key generation and exchange mechanism leverages trust based cluster routing in ad hoc network.
