METHOD FOR BLOCKCHAIN-BASED, ASYMMETRIC KEY MANAGEMENT AND SECURITY-RELEVANT INSTALLATION

摘要

The invention relates to a method for asymmetric key management, particularly in an installation (1) that is relevant to security, in which a key pair consisting of a private and a public key is assigned to each participant (A, B), in which the public key or the hash values thereof are made accessible to the participants (A, B) and are legitimized by a central authority (K) and in which a public key for the central authority (K) is published by a trusted agency. According to the invention, in order to provide an alternative to existing key management systems, the public key or the hash values thereof are verified or read from a register constructed as a blockchain system.
