    摘要: Access of a user to a protected resource during a session is controlled by issuing an authentication information request and receiving authentication information from the user responsive to the authentication information request. The user is authenticated based upon verification of the received authentication information. One or more of the issuing, receiving and authenticating steps are repeated during the session to re-authenticate the user. At least a portion of the authentication information that is used during the re-authentication is different from a corresponding portion of the authentication information that was used during the initial authentication. A secure channel is optionally established between the user and the protected resource responsive to the initial verification. The secure channel can optionally be re-established with the re-authentication using the different portion of the authentication information.

    摘要: A technique provides security to an electronic device. The technique involves disposing a microprocessor between a printed circuit board and a circuit element to restrict physical access to the microprocessor, the microprocessor having (i) a bottom which faces the printed circuit board in a first direction and (ii) a top which faces the circuit element in a second direction which is opposite the first direction. The technique further involves delivering power to the microprocessor from a power source while the microprocessor is disposed between the printed circuit board and the circuit element, the microprocessor performing electronic operations in response to the power delivered from the power source. The technique further involves electronically altering or preventing the microprocessor from further performing the electronic operations in response to tampering activity on the circuit element. Such detection of the tampering activity may involve monitoring a covert signal for tamper evidence detection.

    摘要: A method includes engaging in authentication operations each involving apparent use of a legitimate authenticator. Values of one or more authenticator variables are received and stored, where the authenticator variable(s) normally change in a known authenticator-specific way during the authentication operations, such as being calculated from a monotonically increasing dynamic variable. A risk analysis function is applied to the stored values to generate a risk indicator signal indicating a level of risk that the clone authenticator is in use. The risk analysis function includes detection of an abnormal change of the authenticator variable(s), such as use of non-monotonic dynamic variable values. The risk indicator signal is output to an access controller that operates, based on the level of risk indicated by the risk indicator signal, to selectively inhibit an otherwise successful authentication operation involving apparent use of the legitimate authenticator.

    摘要: A technique of message-passing using shared memory of an RF tag involves storing a message in the shared memory while a security processor of the RF tag is in a sleep mode, the security processor being constructed and arranged to access the shared memory when the security processor is in a wakened mode. The technique further involves transitioning the security processor from the sleep mode to the wakened mode, and processing the message from the shared memory using the security processor after the security processor has transitioned from the sleep mode to the wakened mode. If the security processor is awakened only as needed (rather than remain in the wakened mode), lifetime of a battery which powers the security processor can be maximized.

    摘要: A system for detecting and preventing replay attacks includes a plurality of interconnected authentication servers, and one or more tokens for generating a one-time passcode and providing the one-time passcode to one of the authentication servers for authentication. The system includes an adjudicator function associated with each authentication server. The adjudicator evaluates a high water mark value associated with a token seeking authentication, allows authentication to proceed for the token if the high water mark evaluation indicates that the one-time passcode was not used in a previous authentication, and prevents authentication if the high water mark evaluation indicates that the one-time passcode was used in a previous authentication. The token is associated with a home authentication server that maintains a current high water mark of the token. The home authentication server validates the current high water mark on behalf of the adjudicator function evaluating the token for authentication.

    摘要: Techniques for secure generation of a seed for use in performing one or more cryptographic operations, utilizing a seed generation protocol carried out by a seed generation client (110c) and a seed generation server (110s). The seed generation server (110s) provides a first string to the seed generation client (110c). The seed generation client (110c) generates a second string, encrypts the second string utilizing a key (216), and sends the encrypted second string to the seed generation server (110s). The seed generation client (110c) generates the seed as a function of at leas the first string and the second string. The seed generation server (110s) decrypts the encrypted second string (222) and independently generates the seed as a function of at least the first string an the second string.
