| Abstract | Although flaws have been found out in SSH, the Secure Shell, there has been little discussion about its architecture or design safety. Therefore, considering SSH architecture, e.g. the key exchange protocol, user authentication protocols and total design of the SSH, we not only discuss SSH architectural safety but show critical flaws for SSH users. For establishing the SSH connection, before user authentication, the SSH server and client exchange a session key, which can communicate securely. Then, over the secret channel encrypted by the session key, the SSH server authenticates a user in the SSH client using a user's password or public key. However, owing to defects in the SSH protocols and its design, a user can be deprived of their password in the authentication protocol. Moreover, we show that those who use its public key for authentication are exposed to the same risks as password-oriented users. |

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.
