摘要： A technique carries out seed (or key) derivation within an electronic apparatus (e.g., a hand holdable electronic apparatus such as a token, an authentication server, etc.). The technique involves acquiring a stored representation of a derived seed, the stored representation of the derived seed resulting from an earlier-performed cryptographic operation based on a higher-level seed. The technique further involves (i) performing a current cryptographic operation based on a stored representation of the higher-level seed, the current cryptographic operation resulting in a current representation of the derived seed, and (ii) providing a corruption detection signal indicating whether the current representation of the derived seed matches the stored representation of the derived seed.

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 least 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 and the second string.

摘要： An authentication device comprises a processor having a reset input, a trigger source coupled to the reset input of the processor, and interface circuitry for outputting codes generated by the processor. The trigger source may comprise, for example, a trigger button having an associated switch that when actuated supplies a reset to the reset input. The processor is configured to analyze a given reset applied to the reset input to determine if the reset is an inadvertent reset or a reset generated by the trigger source. The processor generates a code responsive to the reset if the reset is determined to be a reset generated by the trigger source. The code may be supplied to a host device which communicates the code to an authentication server for authentication.

摘要： A technique of authenticating a person involves obtaining, during a current authentication session to authenticate the person, a first authentication factor from the person and a second authentication factor from the person, at least one of the first and second authentication factors being a biometric input. The technique further involves performing an authentication operation which cross references the first authentication factor with the second authentication factor. The technique further involves outputting, as a result of the authentication operation, an authentication result signal indicating whether the authentication operation has determined the person in the current authentication session likely to be legitimate or an imposter. Such authentication, which cross references authentication factors to leverage off of their interdependency, provides stronger authentication than conventional naïve authentication.

摘要： Authentication codes associated with an entity are generated. A stored secret associated with an entity is retrieved. At a first point in time, a first dynamic value associated with a first time interval is determined. A first authentication code based on the first dynamic value is determined. At a second point in time, a second dynamic value associated with a second time interval is determined. A second authentication code based on the second dynamic value is determined. The first and second authentication codes are derived from the stored secret and the amount of time between the first and second points in time is different from the length of the first time interval.

摘要： A technique performs an authentication operation using pulse and facial data from a user. The technique involves obtaining current pulse data from a user, and performing a comparison between the current pulse data from the user and expected pulse data for the user. The technique further involves generating an authentication result based on the comparison between the current pulse data and the expected pulse data. The authentication result may control user access to a computerized resource. Since such a technique uses pulse data, a perpetrator cannot simply submit a static image of a subject's face to circumvent the authentication process. In some arrangements, the technique involves obtaining videos of human faces and deriving cardiac pulse rates from the videos. For such arrangements, a standard webcam can be used to capture the videos. Moreover, such techniques are capable of factoring in circadian rhythms and/or aging adjustments to detect and thwart video replay attacks.
