| Abstract | The DNS Security Extensions (DNSSEC) were developed to add origin authentication and integrity. DNSSEC defined a public key infrastructure over DNS tree hierarchy for the public key validation. In DNSSEC, a parent zone authenticates public keys of its child zones. The authentication hierarchy is broken when a parent does not support DNSSEC. This paper proposes an effective mechanism to overcome this partial deployment problem. Our solution uses a public bulletin board for zones to post their DNSKEY information. Resolvers use posted key information to find key authentication chains that can be used to validate the DNSKEY. Bulletin Board(BB) provides complete trust relationship information when the key authentication hierarchy is broken, and distributes the complete key information even when false zones provide the invalid keys. The bulletin board does not guarantee the correctness of DNSKEY information, but it does guarantee the completeness of the key information. Our approach helps DNS zones to deploy DNSSEC even when their parent zones do not deploy DNSSEC, and it does not require any changes to the current DNSSEC protocol and the existing software. |

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.
