Abstract:
The present invention relates to a system (1 00, 200) and method (300) for protection of user authentication against at least single instance of capture-and-replay attacks, by means of input and processing of user credentials on a client-side user interface (UI), and subsequent transmission to a server undertaking credential authentication. The system (100, 200) and method (300) of the present invention utilizes credentials which are context dependent as inputs into ZK integration function which is additionally applicable as an interaction in two actions: firstly, between user and trusted platform, and secondly between trusted platform and client terminal, as similarly protective of user authentication against capture-and-replay attacks. The user submits credentials as an act of authentication based on context of interest (31 0) as deemed correct by user. Optional verification of the submitted context-dependent credential (320) on the client terminal or trusted platform follows. The method (300) involves ZK integration of the context-dependent credential (330) followed by verification of the authenticator (340), such that unauthorised interception of credentials as submitted does not necessarily result in capability of intercepting party to undertake fraudulent authentication. Verification of user-to-server authentication interaction as being correct is additionally dependent on independent determination by server of context of interest, which might include specification and stratification of time and/or location of the authentication interaction.

Abstract:
The present invention relates to the synthesis of lipophilic or immobilized monobasic phosphate (H 2 PO 4 ) ionophores (7, 8a, 8b and 11) to be used as ion recognition molecules for monobasic phosphate (H2PO 4 ") in the cocktail preparation of hydrophobic polymer membranes in ion selective electrode (ISE) or ion-sensitive field effect transistor (ISFET) chemical sensors for detection of monobasic phosphate (H 2 PO 4 ) ionic species in soil, synthetic media, hydrophonic liquid, tree sap, ground water and rivers.
Abstract:
A method and apparatus (10) for generating random numbers using high-order grating (12) by wave diffraction of emitting photons from the grating (12) is disclosed. The apparatus (10) includes a particle source (11) capable of emitting a source of particles, a high-order grating (12) including output surfaces (22, 23), said high-order grating being disposed in relation to said particle source so that said source of particles encounter said high-order grating (12) for diffraction and particle which goes through constructive interference emits through either output surfaces (22, 23) of said grating (12), and at least one detector for capturing said emitted particle to a random signal to be processed for outputting a random number.
