An electronic device, a method, and a non-transitory, computer-readable medium storing instructions for dynamically verifying trusted applications (TAs) during a boot sequence. The electronic device includes a memory and a processor operably connected to the memory. The processor executes instructions stored in the memory to cause the electronic device to initialize a kernel boot sequence in response to confirming that executable codes for booting the electronic device are from a trusted binary and then verify one or more registered TAs during the kernel boot sequence. Completion of the kernel boot sequence is based on verification results of the set of registered TAs.

System and method for dynamic verification of trusted applications

A connected device includes an application processor, a secure element, and a control module. The application processor is configured to receive a control command from an electronic device. The secure element is connected between the application processor and a control module and is configured to authenticate the control command. The control module is configured to receive the control command when the control command is authenticated by the secure element, execute the control command to activate at least one function of the connected device, and transmit a response to the electronic device.

Authorized control of an embedded system using end-to-end secure element communication

A user device comprising: i) transmit path circuitry and receive path circuitry configured to communicate with a payment server; and ii) processing circuitry configured to control the transmit path circuitry and receive path circuitry. The processing circuitry is further configured to: a) receive a user input related to a payment process; b) calculate a risk score indicative of a likelihood of fraudulent activity associated with the payment process, wherein the risk score calculation is based on confidential information associated with the user that is stored on the user device; and c) transmit to the payment server a payment action and the risk score associated with the payment action without disclosing the confidential information. The confidential information comprises personally identifiable information and/or private information of the user. The processing circuitry calculates the risk score using a risk base model received from a model server.

System and method for fraud detection in a mobile device

An apparatus and method of a hardware isolated secure element protecting a plurality of mission critical subsystems are provided. The method includes performing an actuation operation received across an unsecure path that modifies the state of a mission critical subsystem, performing a diagnostic operation received across the unsecure path that requests state information of the mission critical subsystem, storing information used to determine which of the diagnostic operation and the actuation operation received across the unsecure path are performed, and flashing an execution image of an electronic control unit when the execution image of the electronic control unit is received across the unsecure path.

Apparatus and method for protection of critical embedded system components via hardware-isolated secure element-based monitor

An apparatus and method of an attachment device for interfacing with an on-board diagnostic system of a vehicle is provided. The device includes an application processor configured to receive input from a terminal, control processing of the input by the on-board diagnostic system, transmit a result of the processing of the input by the on-board diagnostic system to the terminal, and a secure element interposed in the communication path between the application processor and the on-board diagnostic system, the secure element configured to filter the input of an on-board diagnostic operation that is untrusted.

Apparatus and method for transparent, secure element-based mediation of on-board diagnostic operations

A method for verifying data integrity of a block device is provided. The method includes providing a secure world execution environment configured to monitor changes to data blocks of a block device, within the secure world execution environment, generating a hash for changed data blocks of the block device, and within the secure world execution environment, verifying and generating a cryptographic signature.
