Abstract
A user apparatus, a base apparatus, and a method for authenticating these apparatuses through exchanging data packets is provided. The user apparatus and the base apparatus are paired, share a set of security algorithms and parameters, and perform a mutual authentication based on the challenge-response authentication mechanism. More in details, each of the challenge data packets includes authentication data (digest_a, digest_b, digest_c) and a set of at least two random sequences having random content and random length, wherein the random sequences are generated excluding those that, in the at least one data packet, produce at least one fake replica of the authentication data that at least one of the apparatuses can erroneously detect.
