The invention provides a physical protection design method for key signals in an SSD main control chip. The method comprises the steps that the number of metal layers is determined according to the number of security levels of the key signals related to data security; the path of the key signal in the SSD chip design netlist is searched, and the wire corresponding to the key signal is designed into the corresponding metal layer according to the security level to which the key signal belongs, the higher the security level of the key signal is, the deeper the wire corresponding to the key signalis, the deeper the metal layer is. According to the invention, the physical safety protection of the SSD main control chip is enhanced.
Description
technical field [0001] The invention relates to the technical field of SSD solid state hard disks, in particular to a design method, system and platform for physical protection of key signals in an SSD main control chip. Background technique [0002] SSD data storage has gradually become the main storage medium for consumer device data storage and cloud storage. For data storage, data security is of great significance, especially for data storage devices related to personal privacy and national security. [0003] The SSD main control chip is the brain of the SSD storage device, and its security performance is particularly important. At present, performance and power consumption are mainly considered in the design of the SSD main control chip. The security of the chip is mainly realized through software. Although the software can resist certain intrusions, it is also very easy to be attacked by hackers and cause data leakage. Therefore, there are certain limitations in impl...
