| Abstract | Most existing attestation schemes deal with binaries and typically require an exhaustive list of known-good measurements beforehand in order to perform verification. However, many programs nowadays are custom-built: the end user is allowed to tailor, compile and build the source code into various versions, or even build everything from scratch. As a result, it is very difficult, if not impossible, for existing schemes to attest the custom-built software with theoretically unlimited number of valid binaries available. This paper introduce SCOBA, a new Source COde Based Attestation framework, to specifically deal with the attestation on custom software. Instead of trying to obtain a know-good measurement list, SCOBA focuses on the source code and provides a trusted building process to attest the resulting binaries based on the source files and building configuration. SCOBA introduces a trusted verifier to certify the binary code of custom-build program according to its source code and building configuration. For custom-built software based on open-source distributions, we implemented a fully automatic trusted building system prototype for SCOBA based on GCC and TPM. As a case study, we also applied SCOBA to Gentoo and its Portage, which is a source code based package management system. Experimental results show that remote attestation, one of the key TCG features, can be made practically available to the free software community. |

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.
