| Abstract | We present a quantum key distribution (QKD) method that allows us to demonstrate practical quantum cryptography. It is used for obtaining the cryptographic key to encode the information communicated between to legitimate parties. It generally relates to a secured key sharing method and system between a plurality of transmitters and a plurality of receivers, more particularly to a system and method of QKD between transmitters and receivers. The aspect of the method is a QKD system capable of forming the first signals with different phases or polarization and the second signals with different delay time. The transmitter sends the two signals to share the key with receiver. The first signal is generated in different phases or polarization to protect the transmission channel and to be the reference time for second signal. The state of first signal and the delay time between the first signal and second signal is the key. The method leads to increase the length of the shared key. This method is used to implement the practical QKD system that can be used for switching between our protocol and BB84 protocol in optical fiber (one-way system) and free space setups with unconditionally security. Secure keys generated by the QKD network are managed in the key management layer by key management agents (KMAs), and used to encrypt the data and send it to receivers. The proposed schemes aimed to provide a secure end to end communication. |

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.
