Application: Processor authentication method (Patent ID: US20240103873A1)
The patent filed by STMicroelectronics NV describes a method for authenticating a processor by receiving decoded operands and signed instructions in an arithmetic and logic unit. The processor determines the operating mode of a printer based on the data from the context register bank and processes instructions accordingly, storing results in the register bank. The method involves generating signature data, signing subsequent instructions, and decoding opcodes to obtain operands for processing in the arithmetic and logic unit.
Furthermore, the patent details a printer with a processing unit that receives opcodes from an ink cartridge and determines the operating mode based on the context register bank data. The printer includes a combination circuit and an arithmetic and logic unit for processing signed instructions and determining processor authorization. The printer's integrated circuit comprises decoding, multiplexer, combination, and arithmetic and logic circuitry to decode opcodes, select operands, generate signed instructions, and determine opcode authorization based on signature data. The signature data includes information from previously processed opcodes, ensuring secure and authenticated processing within the printer.
