Prompt Description

Draw a technology roadmap. Technology Roadmap: Design and Implementation of Secure Interaction Protocols This project addresses the security challenges of interactions between large models and heterogeneous edge devices in intelligent highway operation and maintenance scenarios. It constructs a "layered design, logically progressive, closed-loop evolution" secure interaction protocol system. The overall technical roadmap adopts a horizontal four-stage architecture. First, it solidifies the foundation of trust through a lightweight two-way authentication mechanism, combined with improved Elliptic Curve Cryptography (ECC) principles and binding to the device's unique physical characteristics, to achieve efficient identity verification between heterogeneous devices and large models, with a focus on optimizing execution efficiency for resource-constrained devices. Based on successful authentication, the protocol enters the end-to-end encryption and adaptive protection stage, comprehensively using the SM series of national cryptographic algorithms to encapsulate interaction instructions. This level introduces a critical adaptive key management strategy that can dynamically adjust key parameters based on the risk posture of the current network environment, ensuring absolute confidentiality and integrity of data transmission. On the instruction execution side, this project develops a Trusted Execution Environment (TEE) integration solution to achieve the sinking and closed-loop of security capabilities. It utilizes the hardware security isolation capabilities of edge devices to construct an instruction execution sandbox, isolates and verifies critical operation and maintenance instructions, and supplements it with a real-time behavior monitoring module to strictly prevent malicious instructions or hijacking behaviors. Finally, a protocol security verification framework is established at the top layer of the protocol, using formal verification tools to conduct rigorous mathematical-level analysis of the protocol's core attributes. This not only generates quantitative security assessment reports and compliance inspection conclusions, but more importantly, it and the monitoring data on the execution side together constitute the system's "intelligent evolution" capability. The core feature of this roadmap is its designed dual intelligent feedback loop. The first loop is "environmental perception feedback," driven jointly by the behavior monitoring and protocol verification layers on the execution side, which provides real-time feedback to the adaptive key management module to achieve instantaneous response of security parameters. The second loop is "intelligent strategy optimization feedback," which feeds long-cycle verification and evaluation results back to the underlying authentication module for continuous iteration and optimization of admission strategies. Through these two logical chains, the security protocol is transformed from a rigid execution tool into a dynamic security defense system with self-evolution capabilities, ensuring the reliable sinking of large model operation and maintenance instructions in complex highway environments.
