    摘要: Methods, apparatus and articles of manufacture for decrypting a protected resource on a cryptographic device are provided herein. A method includes decrypting encoded information under a first cryptographic key to access a protected resource, wherein the first cryptographic key is read from a first cryptographic device subsequent to authenticating to the first cryptographic device using a first authentication key, randomly selecting a second cryptographic key, encrypting the protected resource under the second cryptographic key, and writing the second cryptographic key onto the first cryptographic device subsequent to authenticating to the first cryptographic device.

    摘要: Methods, apparatus and articles of manufacture for implementing cryptographic devices operable in a challenge-response mode are provided herein. A method includes storing a set of authentication information in a first cryptographic device associated with a user, receiving a challenge in the first cryptographic device in connection with a user authentication request responsive to a request from the user to access a protected resource, wherein the challenge comprises an index of at least one non-sequential portion of the authentication information stored in the first cryptographic device, and outputting a non-sequential portion of the authentication information from the set of authentication information stored in the first cryptographic device in response to the challenge for use in authenticating the user.
