摘要： A technique controls a soft token running within an electronic apparatus. The technique involves providing an initial series of authentication codes based on a first set of machine states. The initial series of authentication codes is provided from the electronic apparatus to a server through a forward channel to authenticate a user. The technique further involves receiving a command from the server through a reverse channel between the electronic apparatus and the server. The reverse channel provides communications in a direction opposite to that of the forward channel. The technique further involves changing the first set of machine states to a second set of machine states in response to the command, and providing a new series of authentication codes based on the second set of machine states. The new series of authentication codes is provided from the electronic apparatus to the server through the forward channel for user authentication.

摘要： An improved technique for assessing the security status of a device on which a soft token is run collects device posture information from the device running the soft token and initiates transmission of the device posture information to a server to be used in assessing whether the device has been subjected to malicious activity. The device posture information may relate to the software status, hardware status, and/or environmental context of the device. In some examples, the device posture information is transmitted to the server directly. In other examples, the device posture information is transmitted to the server via auxiliary bits embedded in passcodes displayed to the user, which the user may read and transfer to the server as part of authentication requests. The server may apply the device posture information in a number of areas, including, for example, authentication management, risk assessment, and/or security analytics.

摘要： A technique for detecting unauthorized copies of a soft token that runs on a mobile device includes generating a set of random bits on the mobile device and providing samples of the set of random bits, as well as token codes from the soft token, for delivery to a server during authentication requests. The server acquires the set of random bits of the mobile device, or learns the set of random bits over the course of multiple login attempts. Thereafter, the server predicts values of the samples of the set of random bits and tests actual samples arriving in connection with subsequent authentication requests. Mismatches between predicted samples and received samples indicate discrepancies between the random bits of the device providing the samples and the random bits of the mobile device, and thus indicate unauthorized soft token copies.

摘要： A technique provides authentication codes to authenticate a user to an authentication server. The technique involves generating, by an electronic apparatus (e.g., a smart phone, a tablet, a laptop, etc.), token codes from a cryptographic key. The technique further involves obtaining biometric measurements from a user, and outputting composite passcodes as the authentication codes. The composite passcodes include the token codes and biometric factors based on the biometric measurements. Additionally, the token codes and the biometric factors of the composite passcodes operate as authentication inputs to user authentication operations performed by the authentication server. In some arrangements, the biometric factors are results of facial recognition (e.g., via a camera), voice recognition (e.g., via a microphone), gate recognition (e.g., via an accelerometer), touch recognition and/or typing recognition (e.g., via a touchscreen or keyboard), combinations thereof, etc.

摘要： An improved technique provides scheduled data transfer between a mobile device and a server. The mobile device combines token codes generated by a soft token with sequences of auxiliary bits and displays the combinations to users as passcodes. Users may then copy the passcodes to their computers for authenticating to a server on a remote network. As the passcodes include both token codes and sequences of auxiliary bits, a communication channel is established whereby the auxiliary bits as well as the soft token codes are transmitted from the mobile device to the server.

摘要： A processing device comprises a processor coupled to a memory and implements a graph-based approach to protection of a system comprising information technology infrastructure from a persistent security threat. Attack-escalation states of the persistent security threat are assigned to respective nodes in a graph, and defensive costs for preventing transitions between pairs of the nodes are assigned to respective edges in the graph. A minimum cut of the graph is computed, and a defensive strategy is determined based on the minimum cut. The system comprising information technology infrastructure subject to the persistent security threat is configured in accordance with the defensive strategy in order to deter the persistent security threat.

摘要： Knowledge-based authentication (KBA) is provided using historically-aware questionnaires. The KBA can obtain a plurality of historically different answers from the user to at least one question; challenge the user with the question for a given period of time; receive a response from the user to the question; and grant access to the restricted resource if the response is accurate for the given period of time based on the historically different answers. Alternatively, the KBA can be based on historically aware answers to a set of inter-related questions. The user is challenged with the inter-related questions for a given period of time. Historically different answers can comprise answers with applicable dates, or correct answers to the question over time. Historically aware answers can comprise an answer that is accurate for an indicated date or period of time. An accurate response demonstrates knowledge of multiple related personal events.

摘要： Methods and apparatus are provided for embedding auxiliary information in one-time passcode authentication tokens. Auxiliary information is embedded in authentication information transmitted to a receiver by obtaining the auxiliary information; and mapping the auxiliary information to a codeword using a secret key, wherein the secret key is shared between the security token and an authentication authority; and combining the codeword with a tokencode generated by a security token to generate a one-time passcode. The one-time passcode can then be transmitted to the receiver.
