摘要
Access by a requesting entity to an asset is authorized by an access-controlling entity, which transmits to the requesting entity a challenge data set and then receives from the requesting entity a response purportedly corresponding to a representation of the challenge data set in a non-repudiatable form, obtained from an event validation system. The access-controlling entity queries the event validation system to determine whether the response does correspond to a correct representation of the challenge data set in the non-repudiatable form, and authorizes the requesting entity for access only if the response is correct representation. Non-repudiation can be established through entry into a blockchain, or using a hash-tree-based digital signature infrastructure.
