Embodiment Construction

[0014] One or more embodiments of the present invention provide a method and device for performing firmware programming on a microcontroller chip ("MCU chip" for short), and the corresponding MCU chip. The method can be applied to a programming system, and the device can include at least a portion (eg, a portion or all) of the programming system. Based on the method and the device, program codes can be properly protected, especially against various types of attacks, such as reverse engineering or playback attacks, so as to avoid any infringement of rights. For ease of understanding, the MCU chip may include at least one die, and the at least one die may include one or more die, such as including a microcontroller and a non-volatile memory. , NV memory) single die, or a chip stack formed by a die including the microcontroller and a die including the non-volatile memory, but the present invention is not limited thereto. According to some embodiments, the MCU chip may further in...

Abstract

The invention provides a method and apparatus for performing firmware programming on a microcontroller chip and a corresponding microcontroller chip. The method includes: utilizing an integrated circuit (IC) programmer to generate a seed file including characteristic information of the IC programmer; utilizing an encoder to encrypt original data representing a program code at least according to the characteristic information, to generate an encryption version of the original data; utilizing the IC programmer to decrypt the encryption version of the original data according to the characteristicinformation, to generate the original data; utilizing the IC programmer to encrypt the original data at least according to predetermined information, to generate another encryption version of the original data; utilizing the microcontroller chip to decrypt the other encryption version at least according to predetermined information stored in the microcontroller chip to generate the original data,and write the original data into a non-volatile (NV) memory.

Description

technical field [0001] The present invention relates to chip protection, especially to a method and device for firmware programming of a microcontroller chip (microcontroller chip), and the corresponding microcontroller chip. Background technique [0002] A microcontroller chip (referred to as an MCU chip for short) can be applied to electronic products, and various program codes (program codes) executed on the MCU chip can enable the electronic products to have corresponding functions. For example, a manufacturer of electronic products may entrust a solution provider to develop program codes for execution on MCU chips. After completing the design of the program code, the solution manufacturer can release the program code to a third party, such as a programming service provider, for IC programming (IC programming), that is, recording, where the The programming service provider may be an original equipment manufacturer (OEM). After completing the programming work, the progr...
