System-on-chip key management method, apparatus, device, and readable storage medium

Abstract

The invention provides a system-on-chip key management method, a system-on-chip key management apparatus, a system-on-chip key management device and a readable storage medium. A slave device is arranged in a system on chip. The management method is applied to the slave device. The management method comprises the following steps that: an access request sent by a host is received, wherein the accessrequest carries an access address and an access type; a target table item corresponding to the access address is determined, wherein the target table item is one item in a permission table used for performing permission management on the key of the system on chip, wherein the permission table is pre-stored in the one-time programmable memory of the slave device; and the key of the system on chipis managed according to the target table item and the access type. With the system-on-chip key management method, the system-on-chip key management apparatus, the system-on-chip key management device,the readable storage medium of the invention adopted, the security of the key of the system on chip can be improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a system-on-chip key management method, device, equipment and readable storage medium. Background technique [0002] With the rapid development of science and technology, system-on-chip (system-on-chip) is more and more widely used in various fields and is updated more and more frequently. In the whole life cycle of system-on-chip products from design and manufacture to users to replacement or destruction, A system on a chip will flow through different manufacturers, users, and complex environments. The key and key data of each manufacturer and user are stored on the same SoC. These important information need to be opened or closed at a certain stage of the life cycle of the SoC to prevent the leakage of important information in the SoC. This requires The system on chip has a safe and reliable key management mechanism or method, but the current key managemen...
