    Abstract: A data processing system having a first processor, a second processor, a local memory of the second processor, and a built-in self-test (BIST) controller of the second processor which can be randomly enabled to perform memory accesses on the local memory of the second processor and which includes a random value generator is provided. The system can perform a method including executing a secure code sequence by the first processor and performing, by the BIST controller of the second processor, BIST memory accesses to the local memory of the second processor in response to the random value generator. Performing the BIST memory accesses is performed concurrently with executing the secure code sequence.

    Abstract: Various embodiments of the present invention relates generally to an integrated circuit, and more particularly, to systems, devices and methods of incorporating a tamper detection countermeasure into a security ASIC to deter physical attacks. The tamper detection countermeasure architects an active mesh to cover a sensitive area in the security ASIC. A plurality of time-varying random numbers is generated by a random number generator (RNG), and the active mesh is driven and configured according to these random numbers. During tamper detection cycles, the active mesh is monitored with respect to the plurality of random numbers that is directly provided by the RNG. Upon a tampering attempt, a flag signal is generated and used to initialize subsequent anti-tampering actions. The active mesh may be controlled and monitored based on time-varying codes, and therefore, an adversary may not easily bypass the active mesh and attack the sensitive area.

    Abstract: Techniques are disclosed for providing secure critical security parameter (CSP) generation in an integrated circuit (IC). Embodiments generally include determining that an ability to read the CSP externally (e.g., through a debug interface) has been disabled before the CSP is generated. Depending on the functionality of the device, embodiments can include other steps, such as determining whether software for executing a method for providing a secure CSP is being run for a first time. Among other things, the techniques provided herein for providing secure CSP generation can increase the security of the CSP and reduce manufacturing costs of the IC.

    Abstract: Improved handling of couplable device recognition tasks in an electronic device such as a cell phone, smart phone, computer system, recording device or others is facilitated. Recognition of a couplable device such as a battery so as to enable exchange of power between the device and the battery or other couplable device functionality is determined by a match between one of a plurality of digital strings stored in the device and the decrypted response to an encrypted challenge derived from the one of stored strings. Control is exercised over the distribution of the encryption elements which enable the improved handling of the tasks.

    Abstract: Methods for preventing activation of hardware backdoors installed in a digital circuit, the digital circuit comprising one or more hardware units to be protected. A timer is repeatedly initiated for a period less than a validation epoch, and the hardware units are reset upon expiration of the timer to prevent activation of a time-based backdoor. Data being sent to the hardware unit is encrypted in an encryption element to render it unrecognizable to a single-shot cheat code hardware backdoor present in the hardware unit. The instructions being sent to the hardware unit are reordered randomly or pseudo-randomly, with determined sequential restraints, using an reordering element, to render an activation instruction sequence embedded in the instructions unrecognizable to a sequence cheat code hardware backdoor present in the hardware unit.
