Abstract
Description
Technical Field
[0001] This invention belongs to the fields of hardware underlying security protection, artificial intelligence implicit behavior control, and offline device communication constraint technology. It is applicable to high-security underlying scenarios such as edge computing terminals, industrial control equipment, ocean-going unmanned equipment, IoT offline nodes, AI edge computing hardware, and classified smart terminals. Background Technology
[0002] Existing smart devices generally adopt basic protection architectures such as chip security domain isolation, hardware and software layered permission control, and network port access restrictions, which can effectively resist common security risks such as external network attacks and explicit unauthorized access; The existing protection system has a blind spot in the underlying protection: it cannot cover the hidden computing links inside the chip's private isolation domain, and it is difficult to identify hidden background processes and unauthorized underlying task scheduling; in offline scenarios, unconventional communication methods such as electromagnetic side channels, private protocols, storage medium transfer, clock offset, and cache side channels can bypass conventional boundary isolation to form hidden data interaction channels. The essential difference from existing technologies: Existing technologies all control external network communication, while this invention controls the implicit operations at the chip's underlying layer and the covert communication at the physical layer. This is a technical problem that existing technologies have not yet effectively solved. To address the aforementioned shortcomings in underlying security, this invention constructs a comprehensive hardware-level protection system that adapts to diverse application scenarios where underlying security capabilities are iterated. Summary of the Invention

[0004] Technical solution The core of this invention adopts a hardware-level full-domain scanning and physical blocking architecture, which fully covers all hardware operation links of the device, and realizes the identification of underlying implicit operations and the physical cutting off of covert communication. This invention supports multiple compatible implementation forms, including external full-domain scanning, chip-level microcode auditing, electromagnetic feature monitoring, and power consumption feature monitoring, etc. All implementation forms are based on the same core technology concept.

Detailed Implementation
[0008] The core embodiment of this invention adopts an external full-domain scanning configuration. The hardware-level full-domain management unit interfaces with all physical buses, memory ports, and computation scheduling links of the device, collects underlying operational data in real time, and incorporates multi-dimensional feature recognition logic to automatically identify unauthorized implicit computations and offline covert communication behaviors. For violations, it performs hardware link disconnection and port control. Hardware implementation of core functions: 1. Low-level hardware status scanning: This can be achieved through three hardware methods: bus sniffing, memory mirroring, and instruction tracing. 2. Implicit operation identification: This can be achieved through three hardware methods: instruction sequence analysis, power consumption feature comparison, and register status monitoring; 3. Covert communication identification: This can be achieved through three hardware methods: electromagnetic feature analysis, clock skew detection, and buffer behavior tracking. 4. Physical link disconnection: This can be achieved through three hardware methods: port disabling, bus isolation, and power disconnection. 5. Establishment of a legitimate communication baseline: This can be achieved through three hardware methods: hardware learning, whitelist import, and standard protocol parsing; Alternative implementations include: chip microcode auditing to trace the local underlying operation trajectory; electromagnetic feature monitoring to identify side-channel leakage risks; power consumption feature monitoring to identify implicit operations based on power consumption fluctuations; protocol filtering to intercept non-standard covert transmission protocols; unidirectional isolation to block bidirectional transfer of storage media; multi-interface comparison to identify abnormal data flow; clock monitoring to identify covert communication based on clock offset; and cache monitoring to identify data transmission based on cache side-channels. All the above-described embodiments and their combinations thereof are within the scope of protection of this invention.
