Abstract: An apparatus and corresponding method for preventing cloning of code. The apparatus includes a memory, an authentication module, and a device. The memory is configured to store the code, which includes unencrypted code and a fragment of encrypted code. The authentication module is configured to receive and decrypt the fragment of encrypted code from the memory into a fragment of decrypted code, and to store the fragment of decrypted code in an authentication module buffer. The device configured to execute the unencrypted code from the memory and to execute the fragment of decrypted code from the authentication module buffer, wherein the fragment of encrypted code is personalized to the device.

Abstract: Some embodiments of the present disclosure relate to dynamic hardware pad control that is triggered by an intelligent hardware module that monitors an operational state of an IC pin. This hardware module then provides a control signal, which is based on the operational state of the IC pin, to a multiplexer control block that selects one of several different configurations for the IC pin. Because the control signal is provided by the hardware module, the techniques disclosed herein allow precise switching between a number of different IC pin configurations in a fast and efficient manner.
