| Abstract | Vehicles in Vehicular Ad-Hoc NETworks (VANETs) use applications which require an exchange of application-specific confidential data between vehicles. This data must be protected from vehicles not using the application. To achieve this, the vehicles have to authenticate each other in a way that the other communication partner is convinced that the vehicle is eligible to exchange the data. Furthermore, both partners have to agree on an encryption key. This kind of protocols is known as approaches to authenticated key agreement. The proprietary protocol implemented and evaluated in this paper supports these properties and, in addition, preserves the privacy of the vehicles. After executing the protocol, neither one of the participating vehicles nor an eavesdropping third vehicle in communication range can unveil the identity of the vehicles. This important property is achieved by combining the Elliptic Curve Integrated Encryption Scheme (ECIES) with ring signatures. Furthermore, we demonstrate how this protocol can be applied within a GeoNetworking message. We present a prototype of the protocol and discuss evaluation results produced from a test setup with real vehicles. The results show that a feasible ring size can be established to reliably protect the privacy of the vehicles. We also analyse the execution time of the complete protocol, of the constituent protocol steps as well as of the different components like security and transmission. The presented results clearly show that the protocol can be completed on time, even when the communicating vehicles have a high relative velocity and poor communication range. |

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.
