| Abstract | Automatic verification tools, such as model checkers and tools based on static analysis or on abstract interpretation, have become popular in software and hardware development. They increase confidence and potentially provide rich feedback. However, with increasing complexity, verification tools themselves are more likely to contain errors. In contrast to automatic verification tools, higher-order theorem provers use mathematically founded proof strategies checked by a small proof checker to guarantee selected properties. Thus, they enjoy a high level of trustability. Properties of software and hardware systems and their justifications can be encapsulated into a certificate, thereby guaranteeing correctness of the systems, with respect to the properties. These results offer a much higher degree of confidence than results achieved by verification tools. However, higher-order theorem provers are usually slow, due to their general and minimalistic nature. Even for small systems, a lot of human interaction is required for establishing a certificate. In this work, we combine the advantages of automatic verification tools (i.e., speed and automation) with those of higher-order theorem provers (i.e., high level of trustability). The verification tool generates a certificate for each invocation. This is checked by the higher-order theorem prover, thereby guaranteeing the desired property. The generation of certificates is much easier than producing the analysis results of the verification tool in the first place. In our work, we are able to create certificates that come with an algorithmic description of the proof of the desired property as justification. We concentrate on verification tools that generate invariants of systems and certify automatically that these do indeed hold. Our approach is applied to the certification of the verdicts of a deadlock-detection tool for an asynchronous component-based language. |

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.
