Quantum Cryptography & Information Security

Zusatztext

In quantum cryptography, quantum key distribution protocols (QKDPs) employ quantum mechanisms to distribute session key and public discussions to check for eavesdroppers and verify the correctness of a session key. However, public distribution requires additional communication rounds between a sender and receiver. Although, QKDPs allow legitimate participants to establish a session key without initially sharing secret keys and do not need a TC, their security is based on the assumption of authenticated participants. By contrast, classical cryptography provides convenient techniques that enable efficient key verification and user authentication. In this work classical cryptography and quantum cryptography are combined to authenticate users and for successful detection of eavesdropping. Mathematical analysis of the integration is presented. The significant advantage of the integration is, it provides uncompromised security.

Autorenportrait

Quantum cryptography is a new method for secret communications offering the ultimate security assurance of the inviolability of a Law of Nature. In this book we shall describe the theory of quantum cryptography, its potential relevance and the development of a prototype system at HQKDPs, which utilizes the PRISUM TOOL of single-photon interference.
