TRUSTED ATTESTATION METHOD AND COMMUNICATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240346127 titled 'TRUSTED ATTESTATION METHOD AND COMMUNICATION APPARATUS
The abstract of the patent application describes a method for trusted attestation and a communication apparatus. The method involves a first node obtaining information about a blockchain and using that information to determine attestation information, which can be used to remotely attest whether the node is trusted. The information about the blockchain can serve as a common random number generated by the blockchain based on a consensus, which can be used as a challenge value for security measurement by multiple nodes. The attestation information can be verified by any verifier, allowing for measurement once and verification multiple times without the need for a separate challenge-response procedure with each verifier.
- First node obtains information about a blockchain
- Determines attestation information based on the blockchain information
- Attestation information is used to remotely attest whether the node is trusted
- Information about the blockchain can be used as a common random number for multiple nodes
- Blockchain information can be used as a challenge value for security measurement
- Attestation information can be verified by any verifier for multiple verifications
Potential Applications: - Secure communication systems - Trusted computing environments - Remote attestation in IoT devices
Problems Solved: - Ensuring trustworthiness of nodes in a network - Simplifying the attestation process for multiple verifiers
Benefits: - Enhanced security in communication systems - Streamlined attestation process for multiple nodes - Improved trust in IoT devices
Commercial Applications: Title: Secure Communication Systems with Remote Attestation This technology can be applied in industries such as: - Banking and finance for secure transactions - Healthcare for protecting patient data - Government agencies for secure communications
Questions about the technology: 1. How does the method ensure the trustworthiness of the first node? The method uses information from a blockchain to determine attestation information, which can be used to remotely attest the trustworthiness of the node.
2. What are the potential implications of using a common random number generated by the blockchain? Using a common random number can simplify the security measurement process for multiple nodes and improve the efficiency of attestation procedures.
Original Abstract Submitted
a trusted attestation method and a communication apparatus are provided. the method includes: a first node obtains information about a first blockchain, and the first node determines attestation information based on the information about the first blockchain. the attestation information is used to remotely attest whether the first node is trusted. the information about the first blockchain may be used as a common random number that is generated by the first blockchain based on a consensus and that can be used by a plurality of nodes. therefore, the information about the first blockchain may be used as a challenge value for performing security measurement by the plurality of nodes. the attestation information may be verified by any verifier to implement measurement for one time and verification for a plurality of times, so that the first node does not need to establish a separate “challenge-response” procedure with each verifier.
