Abstract: A method of authenticating the communication of an authentication device and at least one authentication server using a local factor with creation of secret information shared by the authentication device and the authentication server; the reference information is derived from the secret information shared by the authentication device and the authentication server, where the manner of derivation is the same on the authentication device and on the authentication server; furthermore, the authentication device creates transformed reference information by means of cryptographic transformation from the reference information, where the local factor chosen and entered by the user or obtained from a medium or from the surrounding environment is used as an input in this cryptographic transformation, and where only the transformed reference information is stored on the authentication device and only the reference information is stored on the authentication server.

Abstract: A method of securing authentication in electronic communication between at least one user authentication mechanism and at least one server authentication mechanism, wherein primary authentication is performed in the first step, and during the primary authentication a secondary authentication secret is created and shared between the user authentication and the server authentication mechanisms and is valid only for the given authentication transaction, and the secondary authentication secret is subsequently used as an input for a cryptographic transformation performed by the user authentication mechanism separately on each authentication vector element while creating the first authentication vector product, wherein authentication vector (AV) is an ordered set of authentication vector elements (AVE)(i)), wherein the first authentication vector product is transferred from the user authentication mechanism to the server authentication mechanism and is evaluated by the server authentication mechanism using the seco
