METHOD AND SYSTEM FOR COMPUTATION AND VERIFICATION OF AUTHENTICATION PARAMETERS FROM INDEPENDANT MEASUREMENTS OF TIME OR LOCATION

摘要

The present invention discloses a method and system for computation and verification of authentication parameters between two entities, an originating entity and a receiving entity, which in the embodiment of interest comprises a server (100), a client interface thereof (110), a human user (120) and a trusted system (130) deemed as such by the human user. The method comprises the user (120) authenticating the server (100) by visual comparison of an authentication code in numeric, symbolic, graphical or visual-interactive form computed by the server (100) in comparison to a plurality of reference codes computed on the trusted system (130); and reciprocally the server (100) authenticating the user (120) subsequent to transcription or transfer of an authentication code, as computed and displayed on the trusted system (130), to the client interface (110) and thenceforth to the server (100), by means of comparison of the test code to a plurality of reference codes computed on the server (100). The method of computation and verification of the authentication codes as aforesaid are by means of zero knowledge (ZK) transformation of time, location or service-specific information; with measurement or determination of time or location information as independently undertaken on server (100) and trusted system (130).
