Abstract

The invention discloses a firmware protection method, device and equipment. The method includes: determining the code length, the code length is at least determined according to the storage attribute value of the charged erasable programmable read-only memory (E2ROM) memory of the firmware to be protected; The attribute value is transmitted by the host computer; according to the encoding length, the abstract syntax mark 1ASN.1 encoding is performed on the initial data transmitted by the host computer to obtain the encoded data; the encoded data is transmitted to the ASN.1 decoder connected to the firmware to be protected; , the ASN.1 decoder is used to perform ASN.1 decoding on the received coded data to obtain initial data and storage attribute values, and send the initial data and storage attribute values ​​to the E2ROM memory of the firmware to be protected, so that the E2ROM memory is stored according to The attribute value is verified for the initial data, and after the verification is successful, the initial data is written into the memory of the firmware to be protected.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to a firmware protection method, device and equipment. Background technique [0002] In recent years, with the development of the network, more and more firmware, such as smart devices in the home and smart devices in the office, have been connected to the network. This gives a lot of opportunities for attackers to invade the firmware by writing illegal files to the firmware to steal user information. [0003] Therefore, a protection method for firmware is needed to prevent attackers from writing illegal files to firmware and stealing user information. Contents of the invention [0004] Embodiments of the present invention provide a firmware protection method, device and equipment to solve the problem of an attacker writing illegal files into the firmware and stealing user information. [0005] In order to solve the problems of the technologies described above, ...
