Providing details for research project descriptions

I'll fill in the placeholders for the Chinese research project description. My focus will be on the key topics: method, framework, key tech, and outcomes. The project involves a distributed, lightweight setup with multiple UAVs in an unstable network environment. I'll also highlight technologies like trust architecture, lightweight authenticators, and efficient cross-domain control.

Building a zero-trust architecture with multi-domain control

I’m focusing on zero-trust principles: continuous verification, least privilege, and assumption of breach. The research involves low-altitude UAVs, ground stations, edge nodes, cloud, and satellites. I'll fill in each section with specific issues like airspace management, dynamic domain partitioning, and identity binding for UAVs with DID and policies for delegation.

Writing section in the specified style

I already have the content I need. Just focusing on the style now, I’ll follow the pattern from the document. I’ll use the structure they outlined starting with headings like “（1）分布式域划分与信任边界模型", then describe issues and goals. I'll cite relevant lines from the provided document to follow their citation requirements clearly.

Crafting the section content for low-altitude trust model

I’ll define the modules for the low-altitude multi-domain setup, including core trust control, edge domain controllers, and various nodes. For the domain partition model, we’ll use terms like ‘空域域’, and I’ll outline the proposed algorithm with considerations like mobility and connectivity. The section will include sub-points on architecture, workflow, boundary attributes, and dynamic evaluation mechanisms, following the established example structure. Let's start with the title and a brief introductory paragraph.

Defining trust model and boundary evolution

For the system, domains include 空管/监管域, 运营域, 任务域, and 服务域. We have a core component managing identity, policy, trust boundary orchestration, and auditing. At the edge, domain trust agents and evaluation sub-engines support UAVs, with an inter-domain trust gateway for cross-domain mapping. The domain evolution process will cover bootstrapping, dynamic joining/leaving, and boundary updates. Trust evaluations will include multiple dimensions, such as identity, device, network, environment, and governance.

Adjusting section and style

The user's request is clear: we don't need additional context from mclick, the snippet is sufficient. We'll follow the document’s style by citing sections that explain trust evaluation. For the rewritten section, I'll remove references to trust or risk scoring and focus on static/dynamic boundary rules. However, I can include terms like "态势/安全状态" as triggers, without implying trust scoring.

Rewriting the section without trust evaluation

We’ll adjust the text as follows:

(1) Distributed Domain Partition and Boundary Model

For low-altitude multi-domain scenarios, we propose examining distributed domain partitioning and boundary models for dynamic access control. Focus areas include multi-domain Zero Trust architecture, domain description, boundary policy enforcement, and context-based constraints. We exclude trust evaluation but introduce boundary constraint element set {B} for managing access and boundary enforcement.

Adapting the structure and citations

For the new section, I'll follow the structure in the document: "首先...其次...然后...最后..." and focus on identity, device attestation, and network context for policy evaluation, not scoring. I'll also include mechanisms for mobility and unstable networks. Citations will reference specific lines where this structure is used, such as L3-L5 for the "我们拟从以下几个角度实施上述思路" part. I'll ensure the writing matches the document style without mentioning "参考文档" or "参考.docx".

Citing document structure cautiously

I’ll follow the structure from the reference document while carefully citing the lines that demonstrate the writing pattern, especially the part with "我们拟从以下几个角度实施上述思路." Since the document includes trust evaluation, I’ll still cite L3, acknowledging that it’s there but making sure the focus stays on the writing style rather than the trust eval content.

Thought for 43s

Adapting zero-trust framework succinctly

The user wants a shorter response, borrowing from a specific document's structure while adapting it. I'll use four brief points, aligning with the document’s order: first, second, then, finally. The trust evaluation part won’t be included, but I’ll still refer to continuous authentication relating to zero trust. I’ll highlight the architecture, especially identity management and edge gateways.

Crafting a concise framework with citations

We’ll format the response around low-altitude domain segmentation based on the structure from the document, referencing identity management, authentication engines, task management nodes, and edge gateways. The response will follow “首先...其次...然后...最后...,” integrating citations without bolding. Key components like the “perception-processing-execution” loop will be included, citing relevant document sections.

Thought for 33s

Citing references and creating diagram

For the citations in my answer, I’ll directly reference the snippets with line numbers, focusing on architecture details like the identity management engine and gateway proxy. I’ll cite specific lines from the documents and use matplotlib to create the diagram with Chinese labels, saving it as an image.

Structuring diagram and final response

I’ll use a three-layer diagram for clarity. Layer 1 will represent the control domains (Regulator, Operator, Mission), with boxes for key components. Layer 2 will illustrate the edge network, showing edge nodes and their features. Layer 3 will illustrate UAVs, control terminals, and resources. I'll include arrows to show interactions and provide a file link with the image and a brief explanation. This seems to align with the user’s request for the framework illustration.

Creating diagram for system model and zero trust architecture

User asked for a diagram of a system model with a focus on zero trust. I’ll design it to include multi-domain UAVs, subjects/controllers, nodes like ground station, edge nodes, and regulatory components. I’ll also mention risks like fake identities and device takeover, as well as zero trust elements. No need to reference the Word file again in the diagram response.

Generating the diagram with image tool

After generating the diagram with the image tool, the response will be empty as required. The user will see the image displayed. I need to make sure the prompt is clear, in Chinese, with a 16:9 layout, white background, and crisp, sans-serif Chinese fonts. I'll proceed with crafting that.

Designing diagram with distinct regions and key components

User wants the diagram to have three distinct regions: the left side showing “未来低空多域互联场景” with icons of UAVs crossing domains; the central region focusing on "零信任可信认证与授权架构" with layers; and the right side showing “安全目标.” I’ll include elements like UAVs, edge nodes, multi-domain controllers, and cross-domain connections. I'll also include details such as continuous authentication, cross-domain evidence mapping, and dashed links for weak connections.
