NOVELTY – The method involves initializing and selecting elements to form a key and determining parity of the elements. A segment value and a recovered value are calculated, and a cryptographic key pair is generated using parameters of PD domain and seed. Access control and/or authentication in electronic services are performed. USE – Symmetrical insurance identification method for a user equipment on windows platform. ADVANTAGE – The method enables obtaining the full content of the user hard disk, improving the security analysis of a user hard disk and providing the protection level suitable for applications. DESCRIPTION OF DRAWING(S) – The drawing shows a graph illustrating a symmetrical insurance identification method.
