| Abstract | SIP (session initiation protocol) [1] is widely used in Internet as a signaling protocol for VoIP (voice over IP) and multimedia services. Recently, there have been some efforts to propose peer-to-peer SIP (P2P-SIP) architecture, which makes use of a peer-to-peer network instead of registrar and location SIP servers in order to facilitate SIP user registration and location. One of main issues in P2P-SIP is authentication of resource such as SIP user information without an authentication server. In order to authenticate the resources in P2P-SIP, the signature can be attached to the end of SIP message under PKI (Public Key Infrastructure) framework. However, the PKI-based signature model in P2P-SIP requires verification of central authorities (CA) during SIP message routing and certificates maintenance of intermediate nodes for authentication procedure. It causes much delay in signaling as users increase in P2P-SIP. Especially, much delay in signaling of real-time multimedia communication can be a significant problem. In this paper, we propose an efficient resource registration and location scheme in P2P-SIP, using ID-based signature which has more light-weight authentication procedures. ID-based cryptography is firstly proposed in [2], which is signature scheme, based on the bilinear pairings on elliptic curves. ID-based signature allows users to verify digital signatures using only public information such as the user's identity, while PKI-based signature requires verification of each user's public key from CAs. It can utilize public identifier such as e-mail ID or SIP-URI as a public key, so that it reduces the complexity and costs for establishing and managing the public key of nodes. In this paper, we identify efficiency of this resource registration and location scheme, using ID-based signature in comparison with PKI-based signature model through simulation. |

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.
