The quantum cryptographic key assignment problem is getting important in an optic network, when it is to assign cryptographic keys to each of communication parties via insecure optic channel. In this paper, we propose Three-Party Authenticated Quantum Key Distribution Protocol with Time-Bound (3PAQKD-TB). Each session key corresponding to the measurement bases dynamically changed for each time-period,...
We propose a time constraint three-party encrypted key exchange protocol in which both two parties/clients only act as the roles within the relationship of exchanging secure messages constrained by the intersection time periods. The technique of time constraint, in this paper, is that a trusted server generates a serial of secure exchanging messages, which are used to generate multiple session keys...
