INTRODUCTION 1.1About the Project Existing clay In classical cryptography, three-party spot diffusion protocols give challengeresponse mechanisms or ti mestamps to prevent replay attacks.

However, challengeresponse mechanisms require at least(prenominal) two communication rounds between the TC and participants, and the timestamp go on needs the assumption of clock synchronization which is not functional in coverd systems (due to the unpredictable nature of network delays and potential contrasted attacks) . Furthermore, classical cryptography cannot detect the existence of passive attacks such(prenominal) as eavesdropping. This fact can then be apply to center the number of rounds of other protocols based on challenge-response mechanisms to a indisputable center (and not only three-party documented key distributio n protocols). Limitations of Existing Sy! stem Disadvantage of separate calculate on 3AQKDP and 3AQKDPMA were provide the authentication only for message, to identify the pledge travel in the message. Not identify the security go in the session key. Proposed System In quantum cryptography, quantum key distribution protocols (QKDPs) employ quantum mechanisms to distribute session keys and public discussions to check for eavesdroppers and corroborate the correctness of a session key. However, public discussions require superfluous communication...If you want to describe a full essay, order it on our website: OrderEssay.net
