| Abstract | We begin with overviews of the existing defects of the current Kerberos protocol and the shortage of the current improvement, and then we focus on the new method of the dynamic password and public key. On the basis of the original Kerberos protocol, firstly, we propose the usage of the Diffie-Hellman algorithm, and put the password in the token, then take the key which has added the dynamic factor as the sharing key between Client and AS, this improvement can fundamentally solve the password guessing attack. Secondly, we use the method of the ElGamal algorithm. For one thing, it will generate a new public key in each authentication, and put the new public key as the secret key of the information transmission between client and resource server, this method basically guarantees security of the information transmission; For another we use the random number, which is associated with the public key, to take the place of the time-stamp to prevent replay attack, it puts the random number and our key together to increase the ability of preventing replay attack. Finally, we analyze the example of the improvement which has been carried out. And the results show that the improved Kerberos protocol can ensure the security of the information and password. |

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.
