| Abstract | Many security-critical web applications, such as online banking and e-commerce, require a secure communication path between the user and a remote server. Securing this endto- end path is challenging and can be broken down into several segments. The network part between the user’s machine and the server is usually well protected, using secure communication protocols, such as the Transport Layer Security (TLS) protocol. However, the user’s sensitive inputs (such as password and credit card number) are handled by the operating system (OS) and the web applications before being encrypted and passed on to the network; also some sensitive information from the server (such as private account balance and transaction confirmation) is handled by OS/applications before being displayed to the user. This user interface part of the communication path, which includes the OS and web applications, is often untrusted because of possible malware (virus, rootkits, spyware, etc.) and vulnerabilities within the client. In this paper, a secure user interface running under an untrusted OS is proposed, which is independent of the OS/applications and has a very small code base size. This secure user interface attests itself to the remote server and then handles the sensitive input and output by itself, bypassing the OS kernel and web applications. It utilizes network software stacks in the OS, however, the sensitive information is cryptographically protected before being revealed to the potentially malicious OS. This ensures the confidentiality and integrity of the sensitive information. Using this secure user interface, even while running under untrusted OS/applications, the user’s sensitive input, private output, and transaction integrity can be protected. |

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.
