  • Publication number: 20240005004
    Abstract: A system and method are provided that enable a processor to have the immutable code and data that it uses for its boot process to be securely patched. A system may include a read only memory (ROM) storing one or more certificates and instructions, an array of one-time programmable (OTP) indicators, a bootstrap controller connected to the ROM and the array of OTP indicators, and a random access memory (RAM) connected to the bootstrap controller. The bootstrap controller is configured to verify integrity of firmware for boot based on certificates stored in ROM, check for a patch in the array of OTP indicators, and write the one or more certificates and the instructions in ROM and the patch into the RAM. The patch may be loaded into RAM by the bootstrap controller and overwrite ROM instructions or certificates in RAM.

  • Publication number: 20240003972
    Abstract: A system and method are provided that enables a processor to undergo a functional test of its circuits prior to attachment to a semiconductor package and prior to use in a computing platform. The method of testing chips includes attaching a non-packaged semiconductor circuit to a test bed, loading computer instructions into a memory of the non-packaged semiconductor circuit, and operating the non-packaged semiconductor circuit in a test boot mode and executing the computer instructions in that mode. The operation logs one or more events of the execution of the instructions in the test boot mode and transmits the logs of the one or more events from the non-packaged semiconductor circuit via a joint test action group (JTAG) interface or a universal asynchronous receiver/transmitter (UART) interface.

  • Publication number: 20230083979
    Abstract: A system and method is provided that enables a processor to undergo RMA after being in a secured operating state, where the secure state includes hardware disabling of test access ports and debug ports during a boot process. The apparatus providing this computer security at power-on or boot-up may have at least two one-time programmable indicators, a bootstrap controller that controls at least two boot-time switches and reads the one-time programmable indicators, and a read only memory storing at least one instruction. The bootstrap controller calculates an operating state such as a secure state or RMA state based on the at least two one-time programmable indicators. The bootstrap controller then enables or disables an execution of the at least one instruction or enables or disables a hardware port based on the operating state. The bootstrap controller may provide switching between RMA and secure states via sequential one-time programming of indicators.

  • Patent number: 11459555
    Abstract: The present invention relates to a method of purifying native ubiquitin without acid or heat treatment. The method presented here is designed to overcome limitations of acid or heat based ubiquitin purification in two different points of view. First, it decreases a chance of mixing other proteins resistant to acids or heat. Second, it includes no harsh condition, which might denature the ubiquitin. As a result, the purification of native ubiquitin becomes possible. The ubiquitin obtained herein is expected to be used for various purposes in technical fields.
