| Abstract | VoIP is a telephony application which transmits the compressed voice in packets over the Internet. The voice packets are subject to eavesdropping on the public network, since the Internet possesses the inherent security vulnerabilities. In order to protect users' privacy and voice packets confidentiality, an authentication module with encryption should be imposed during VoIP communications to ensure secure voice call. In this paper, we propose an authenticated key agreement protocol based on ECC. The proposed protocol negotiates the secret session key and then employs the well-known AES encryption algorithm to encrypt/decrypt the voice packets with the session key for privacy protection. We deploy the scheme on a SIP-based VoIP phone over the local network. The results from our experiments demonstrate that our proposed scheme not only provides secure VoIP call, but also preserves the quality of real-time voice, which is vital to VoIP applications. |

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.
