Remote Attestation Mode Negotiation for Network Device Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote attestation systems require manual static configuration of attestation modes, which is inflexible and labor-intensive, especially when dealing with a large number of network devices, leading to high labor costs and inefficiencies.
Innovation Solution
Implementing a method for automatic negotiation between network devices and servers to determine a remote attestation mode dynamically, reducing the need for manual configuration and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual static configuration is used to determine remote attestation modes for network devices, then configuration accuracy can be ensured, but labor costs increase and flexibility decreases
Solution Approach 1:
The network device automatically determines its remote attestation mode by sending capability indication information to the server and receiving determination results, eliminating the need for manual configuration while maintaining accurate mode assignment through automated negotiation
Solution Approach 2:
The system implements a feedback mechanism where the network device reports its supported attestation modes to the server, the server determines the appropriate mode based on this feedback, and then configures the device accordingly, creating a closed-loop automated configuration process
2Stability of the object's composition
If manual static configuration is used for remote attestation modes, then configuration stability is maintained, but adaptability to different device scenarios deteriorates
Solution Approach 1:
The remote attestation mode configuration transitions from static manual assignment to dynamic automated negotiation, where the mode is determined based on real-time device capabilities and server requirements, enabling the system to adapt flexibly to different scenarios while maintaining stability through standardized negotiation protocols
Solution Approach 2:
The system changes the configuration parameter determination method from fixed manual values to dynamically negotiated values based on device capability parameters, allowing the attestation mode to adapt to different device types and scenarios while maintaining systematic control
3Productivity
If automatic negotiation is implemented for remote attestation modes, then labor costs are reduced and flexibility improves, but system complexity increases
Solution Approach 1:
The automatic negotiation process is segmented into distinct functional modules: capability indication information generation, server-side mode determination, and configuration application, which reduces implementation complexity by breaking down the automated negotiation into manageable, standardized steps
Solution Approach 2:
The negotiation mechanism is designed as a universal protocol that can handle multiple device types and attestation modes through standardized capability indication and determination processes, reducing the need for device-specific complex logic while maintaining high productivity

AI summary
This application discloses a remote attestation mode negotiation method and apparatus. Before remote attestation is performed, automatic negotiation is performed between a to-be-verified network device and a server, so that the to-be-verified network device and the server can determine, through negotiation from remote attestation modes supported by both the to-be-verified network device and the server, a remote attestation mode used to subsequently perform remote attestation between the network device and the server, and there is no need to manually statically configure a remote attestation mode for the network device and the server, thereby greatly reducing labor costs of determining the remote attestation mode. In addition, when there are a large quantity of devices, the automatic remote attestation mode negotiation method also helps configure a remote attestation mode more flexibly.
