AI Technical Summary
Existing data gateways lack sufficient security, are vulnerable to security risks from foreign chip firmware, rely solely on Level 1 trusted security certification, and lack proactive defense and systemic security protection, thus failing to effectively guarantee the security of data collection, processing, storage, and transmission.
The security gateway system based on PSPA architecture includes a secure boot subsystem, a port driver security subsystem, a protocol security authentication subsystem, a data storage security subsystem, a key management subsystem, a system security authentication subsystem, an application scheduling subsystem, and a trusted application (TA). It constructs a trusted execution environment and a rich execution environment to achieve security for secure boot, data transmission, storage, and upload.
It improves the overall security of the data gateway by using domestically produced chips and multi-level trusted boot to prevent vulnerabilities in foreign chip firmware, achieving proactive data immunity and systemic security protection, and ensuring data security at every stage.
