Disclosed is a method for mutual authentication between a station, having a digital rights agent, and a secure removable media device. The digital rights agent initiates mutual authentication by sending a message to the secure removable media device. The secure removable media device encrypts a first random number using a public key associated with the digital rights agent. The digital rights agent decrypts the encrypted first random number, and encrypts a second random number and a first hash based on at least the first random number. The secure removable media device decrypts the encrypted second random number and the first hash, verifies the first hash to authenticate the digital rights agent, and generates a second hash based on at least the second random number. The digital rights agent verifies the second hash to authenticate the secure removable media device.

L'invention concerne un procédé d'authentification mutuelle entre une station, ayant un agent de droits numériques, et un support amovible sécurisé. L'agent de droits numériques déclenche une authentification mutuelle en envoyant un message au support amovible sécurisé. Le support amovible sécurisé crypte un premier nombre aléatoire en utilisant une clé publique associée à l'agent de droits numériques. L'agent de droits numériques décrypte le premier nombre aléatoire crypté, et crypte un second nombre aléatoire et une première information parasite sur la base d'au moins le premier nombre aléatoire. Le support amovible sécurisé décrypte le second nombre aléatoire crypté et la première information parasite, vérifie la première information parasite afin d'authentifier l'agent de droits numériques, et génère une seconde information parasite sur la base du second nombre aléatoire au moins. L'agent de droits numériques vérifie la seconde information parasite afin d'authentifier le support amovible sécurisé.
