Abstract
The invention relates to an authentication method. The method comprises: collecting, based on a predetermined authentication policy, at least one context data element; constituting, based on the at least one collected context data element, a data packet; generating, by using a predetermined hash type algorithm and the data packet, as input to the predetermined hash type algorithm, a hash; sending the generated hash; generating, as a hash distance generation step, a hash distance between the generated hash and a predetermined reference hash; and authenticating successfully or not based on the generated hash distance, as an authentication step. The invention also relates to corresponding device and system.
