Vehicular Ad-hoc network a subclass of Mobile Ad-hoc network with various features providing Vehicle-to-Vehicle communication, Vehicle-to-RSU communication, Vehicle-to-Trusted Authority Communication. VANET is gaining higher attention now days both in industry and academic area and has become a trending research topic for research but still a lot of improvements is required in this area. Security of data is one of the major challenge in VANET. Encryption of data with the help of various encryption algorithms came up as solution for securing communication in VANET. But existing encryption algorithms used to secure VANET’s are complex due to which data are not delivered on time and face a lot of problems like privacy of data ,non-repudiation and cost (i.e. communication cost, computational cost).In our proposed scheme we use a hybrid approach, which contain ECC algorithm( asymmetric algorithm).ECC algorithm is used for encryption of personal details (i.e. Speed, location, device address) and AES algorithm (symmetric algorithm ) is used for encryption for safety messages along with output of ECC algorithm. The objective of this hybrid approach is to perform double encryption on personal details for more privacy of personal data (using ECC and AES algorithm) and single encryption on safety messages (using AES algorithm) so safety messages are delivered on time and without any delay.

Mobile Ad Hoc

Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. Although the ongoing trend is to adopt ad hoc networks for commercial uses due to the property of its capability in forming temporary network without the aid of any established infrastructure or centralized administration. Due to this unique property, the main challenge is the vulnerability to security attacks. A number of challenges like open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc. are posed in MANET. As MANET is quickly spreading for, security challenges has become a primary concern to provide secure communication. In this paper, we identify the existent security threats an ad hoc network faces, the security services required to be achieved and the countermeasures for attacks in each layer. To accomplish our goal, we have done literature survey in gathering information related to various types of attacks and solutions, as well as we have identified the challenges and proposed solutions to overcome them. In conclusion, we focus on the findings and future works which may be interesting for the researchers like robust key management, trust based systems, data security in different layer etc. However, in short, we can say that the complete security solution requires the prevention, detection and reaction mechanisms applied in MANET.

Incessantly a self configuring network for mobile devices known as Mobile Ad hoc Network (MANET) are associated wirelessly .In significant networks, this design might perhaps enforce increased computational costs owing to the costly credentials chaining overheads that would not adapt for ad-hoc applications with increased nodes. Here a survey is carried out to express a view on the secure and authentic MANET systems. The literature reviewed is on different and diverse techniques of related to MANET systems. Reviews of 65 papers is presented and stated the significant analysis. At first the analysis depicts various attacks that are contributed in different papers. Subsequently ,various measures like security, cost, simulation time etc are also analyzed. It analyses the encryption method also that is exploited in each paper. This paper further gives an insight regarding the tools adapted ,chronological review and performance achievements in each case. At the end the review extended for the different research issues to investigate further research on secure and authentic MANET system

Recent progression in the field of information and communication cause increase of packet count over the World Wide Web network. These communicated packets should deliver on time from origin node to destination node using a reliable and shortest route. In this way routing plays an important part in dispatching the packets to destination form the source. This routing becomes more crucial when packets delivery is done in independent mobile nodes which dynamically form a temporary network. This network named as Mobile Ad-Hoc Network and therefore it is said to be particular reason-specific, self-ruling and dynamic. In this paper we analyzed 3 protocols and for a quality of service (i.e., Packet Delivery Ratio) and achieved comparative study of various protocols of routing with respect to Operation of protocols, Route maintenance, Routing table, Route, Route selection, Routing structure, Routing Approaches, Protocol types, Merits and Demerits.
