  • Patent number: 11398910
    Abstract: Systems and methods of the invention are directed to provisioning a token by a secure authentication system. A user may initiate a transaction that causes a resource provider computer to transmit an authentication request message to a directory server computer. The directory server computer may transmit the authentication request message to an access control server computer for authentication. Subsequent to receiving the authentication request message, the directory server computer may request a token for the transaction from a token provider computer. If authentication is successful, the token may be included in an authentication response message transmitted by the directory server computer to the resource provider computer. The token may then be utilized by the resource provider computer in lieu of sensitive user information for any suitable purpose. In some embodiments, user-specific-data provided by the access control server computer may be included in the authentication response message.

  • Patent number: 11399043
    Abstract: Embodiments of the invention are directed to the utilization of trust tokens to perform secure message transactions between two devices. A trust token transmitted in a message from one device may include first data that is digitally signed by a trust provider computer, and second data that is digitally signed by the device itself. Upon receipt of a message containing a trust token, the recipient may utilize the first data to verify with the trust provider computer that the sender of the message is a trusted party. The trust provider computer may provide the recipient device the public key of the sender. The recipient may utilize the second data and the provided public key to verify that the sender signed the message and that the message is unaltered. These techniques may increase detection of relay, replay, or other man-in-the-middle attacks, decreasing the likelihood that such attacks will be successful.

  • Patent number: 11372981
    Abstract: A redundant processing system with profile-based monitoring is disclosed. In embodiments, the redundant system includes two or more redundant lanes, each lane having equivalent processing components. In a testing state, template processors and hardware monitoring sensors are connected to a selected trusted lane and input vectors submitted thereto; the hardware sensors characterize the response of the selected lane and the resulting testing data compiled into system templates. In an operational environment, the template processors send challenges based on the input vectors to each of the redundant lanes in real time, collecting response data from each lane via identical sets of monitoring sensors. The template processors correlate the response data with the corresponding system templates, identifying anomalous lanes and system anomalies based on discorrelations between the response data and the system templates.

  • Patent number: 11349849
    Abstract: This disclosure describes embodiments of an improvement to the static group solution because all the administrator needs to do is specify the criteria they care about. Unlike static groups, where the administrator needs to keep track of the status of individual users and move them between static groups as their status changes, smart groups allows for automatic identification of the relevant users at the moment that action needs to be taken. This feature automates user management for the purposes of enrollment in either phishing and training campaigns. Because the smart group membership is determined as the group is about to be used for something, the smart group membership is always accurate and never outdated. The query that determines the smart group membership gets run at the time when you are about to do a campaign or perform some other action that needs to know the membership of the smart group.

  • Patent number: 11310243
    Abstract: An example intermediary system allows an owner computer system to securely identify and communicate with an end device. The end device uses master secret and time data shared with the owner computer system to generate and advertise a time-dependent device identifier and potentially an encrypted device message. The intermediary system augments the received device data with a message (e.g., an estimate of the device's location) encrypted using the time-dependent device identifier as an encryption key. Furthermore, it hashes the time-dependent device identifier for additional security. The augmented data is forwarded to a server for retrieval and processing by the owner computer system. The owner uses the shared master secret, time data and hash function to generate a hashed time-dependent device identifier used to retrieve matching augmented data from the server. The retrieved message data is decrypted using the reverse of the encryption operations.

  • Patent number: 11271730
    Abstract: Dynamic Cipher Key Management (DCKM) of the present invention enables the protection of sensitive electronic data by assigning symmetric or asymmetric cipher keys using a process that delivers the cipher key to a network endpoint device by means of a key installation, delivery, and storage methodology. DCKM may negate the need to physically touch the network device under protection. Further, DCKM's process is based on a set of operating principles that maintains the highest levels of assurance that the cipher key pairs are issued with only devices that have the right and authorization to create a secure communication path. The DCKM process realizes the same level of security confidence that is only achieved today with conventional token based key management services with respect to the paired devices linked via a cipher key public and private relationship.

  • Patent number: 11269977
    Abstract: System and method of collecting and processing data in electronic devices. A sensors data collector collects measurements from at least an accelerometer and a gyroscope of an electronic device. A data-loss prevention module operates to pass these measurements, immediately upon their collection, to a supplemental locally-running processing thread which retains the measurements even after a refresh of a web-page in which the measurements were collected, and which transmits the measurements to a remote server even after refresh of the web-page in which the measurements were collected. Non-global scope of functions is utilized, to reduce security exposure. An asynchronous SharedWorker module is utilized, to alleviate congestion of computing resources of the electronic device. Data obfuscation and encoding is utilized to maintain anonymity of user-entered data while still allowing a remote server to ensure the integrity of data received from the electronic device.
