| Abstract | Recently the security in vehicular ad hoc networks (VANETs) draws attention because of increasing vehicular applications. One of the main challenges of secured communication in VANET is multicast source authentication which essentially guarantees that the received data in communication is genuinely sent from the source and not modified by impersonators. Although much research has been focused on message authentication, there are no general accepted solutions widely used for source authentication in VANET because of its dynamic network topology and complicated membership management. In this paper we proposed a Group-based Source Authentication protocol (GSA) to handle the message authenticity in VANETs. Many VANET applications have natural group property and VANET nodes follow the similar moving pattern. GSA makes use of group attributes as dynamic group key to protect data transmission in intra-group communication, which is dynamic changing with real-time environment and consistently updates among group members. Then GSA deploys the promising TESLA scheme to perform source authentication in inter-group communication. The results from our implementation show that GSA can guarantee multicast source authenticity and significantly enhance the efficiency of authentication for multicast communication in VANETs, and our implementation testbed also shows that GSA scheme can be easily deployed in real VANET environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
