Description

Technical Field

[0001] The present invention relates to the technical field of Block SID conversion state testing, and in particular to a method, device, computer equipment, and storage medium for testing the Block SID conversion state of a solid-state drive. Background Art

[0002] Block SID (Block Security Identifier) ​​is an advanced data storage security policy developed by the Trusted Computer Group. It protects users' storage devices from ransomware attacks, malware attacks, and data tampering, thus preventing unnecessary losses. Any peripheral trusted storage SSD product compatible with Block SID must comply with the Trusted Computer Group's Block SID specification. This security policy utilizes hardware-based self-encryption, offering significantly higher performance and security than software-based encryption. When a Block SID-enabled SSD storage device communicates with a platform as a trusted peripheral, enabling Block SID authentication effectively prevents hackers and host software from using the default SID (Security Identifier) ​​to attack, ransom the SSD user, or steal and tamper with the SSD's data, effectively protecting the SSD user's data security. Therefore, it is crucial to test whether SSDs correctly enable Block SID authentication and disable it according to the conditions defined in the specification. If Block SID authentication-compatible peripheral trusted storage SSD products cannot enable and disable Block SID authentication according to the conditions defined in the specification, SSD users are likely to be subject to ransomware and malware attacks by hackers and data tampering, resulting in irreparable losses and greatly affecting users' experience and trust in secure storage products.

[0003] Currently, the enabling and disabling of Block SIDs is typically controlled by the BIOS (Basic Input Output System). The TCG_Storage-Feature_Set_Block_SID_Authentication specification, developed by the Trusted Computer Group (TCG), stipulates that Block SID security authentication should be disabled after a recovery method, a TCG hardware reset, or a platform power cycle. TCG hardware resets include multiple sub-events, such as a PCI (Peripheral Component Interconnect) hot reset and an NVMe subsystem reset. Without the BIOS source code, secondary development and testing of the various factors affecting Block SIDs is difficult. Furthermore, the confidentiality and cost of BIOS source code are extremely high, and its logical structure is complex. Secondary development of the code places extremely high demands on SSD testing professionals, making it difficult to meet these requirements. Summary of the Invention

[0115] S18, power off and then power on the solid-state drive, and modify the factory default password to form a 010 combination state;

[0116] Among them, when the factory default password is changed, the 101 combination state changes to the 010 combination state.
