| Abstract | In this paper we introduce a ticket distribution scheme for Fast re-Authentication protocol (FAP) for inter-domain roaming. FAP is designed to reduce the authentication time of a mobile user in a visited administrative domain. The approach eliminates the need for communication between the visited network and the subscriber's home network for credentials verification and uses a short-living lightweight re-authentication ticket, which does not require a revocation mechanism. To minimize the number of authentication tickets sent to each subscriber, we propose the use of a neighbor table, which is maintained by an authentication server of each network. When the client requests a ticket, the server generates tickets only for the networks contained in the line of the neighbor table corresponding to the current location of the user. This method decreases the number of tickets sent and, consequently, the overhead and the delay of the ticket acquisition phase of the protocol. To create this neighbor table, we propose a reactive mode for the ticket acquisition phase. In this mode, the server sends tickets on demand of the client and only for the selected target network. Numerical results obtained from experiments on a test-bed and a series of simulations show that the proposed scheme enhances inter-domain handover parameters such as authentication latency and signaling cost. |

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.
