Three Party Authentication Key Distributed Protocols Using Implicit and Explicit Quantum Cryptography
Journal Title: Indian Journal of Computer Science and Engineering - Year 2011, Vol 2, Issue 2
Abstract
Cryptography is the science of information security. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. The combination of Implicit quantum key distribution protocol (3AQKDP) and explicit quantum key distribution protocol (3AQKDPMA) are used to form the new combination and demonstrate the following merits: Establishment of a secure connection which can prevent attacks such as eavesdropping, man-in-the-middle and replay. Reduction in communication rounds among existing QKDPs, improves efficiency of proposed protocols. A long term secret key can be used and shared between two parties repeatedly. Classical cryptography methods currently used are unsafe and cannot detect the existence of passive attacks such as eavesdropping. Hence the combination of both classical as well as quantum cryptography is proposed.
