Fast Convergent and Secure Key Distribution Protocols Using a Dual-Quantum Channel
(2008)This dissertation presents three new quantum key distribution protocols over a dual quantum-channel to enhance the convergence speed of the key distribution process. The proposed protocols effectively use a dual-quantum ... -
FINDING MINIMUM GAPS AND DESIGNING KEY DERIVATION FUNCTIONS
(2011)"While the priest climbs a post, the devil climbs ten". The problem size gets larger as computers become faster. Using naive algorithms, even equipped with fast CPUs and large memories, computers still cannot handle many ... -
QUANTUM SECURE COMMUNICATION USING POLARIZATION HOPPING MULTI-STAGE PROTOCOLS
(2016)This dissertation presents a study of the security and performance of a quantum communication system using multi-stage multi-photon tolerant protocols. Multi-stage protocols are a generalization of the three-stage protocol ... -
Study of Matrices Related to Discrete Logarithm in Kummer Extensions
(2016)The discrete logarithm problem has been studied during the past decades for its important application in cryptography and other fields. It is very useful in the public key cryptography, which is widely used for Internet ...
