    Abstract: Input signals may be received. Furthermore, a control signal controlling the implementation of a Differential Power Analysis (DPA) countermeasure may be received. One of the input signals may be transmitted as an output signal based on the control signal. A cryptographic operation may be performed based on the first output signal that is transmitted based on the control signal.

    Abstract: A computing device receives a feature name or key name for an integrated circuit comprising a security manager core and an additional component. At least one of a) the additional component is associated with the key name or b) a feature provided by the additional component is associated with the feature name. The computing device receives a specified number of bits associated with the feature name or the key name, and maps the feature name to a feature address space or the key name to a key interface of the security manager core based at on the specified number of bits. The computing device generates at least one hardware description logic (HDL) module based on the mapping, wherein the at least one HDL module is usable to configure the security manager core for delivery of payloads associated with the feature name or the key name to the additional component.

    Abstract: Systems and methods for implementing access control by systems-on-chip (SoCs). An example SoC may comprise an access control unit employed to: receive a message comprising an access control data item; validate the message using a value of a message digest function of contents of the message and a value of a state variable reflecting a state of communications between the access control unit and a programming agent that has initiated the message, wherein the value of the state variable is derived from a previous value of the message digest function calculated within a current communication session between the access control unit and the programming agent; update the state variable using the value of the message digest function of the contents of the message; and control, using the access control data item, access by an initiator device to a target device.
