Blockchain network entity protection method

Blockchain network entity protection method

Application of blockchain technology:

Decentralized trust establishment: Utilize the decentralized characteristics of the blockchain network to establish an access control system that does not require a third-party trust mechanism.

Transaction transparency and immutability: All access transactions are recorded on the blockchain to ensure that transactions are transparent and immutable.

Game mechanism for access authorization:

Game types and strategies: A variety of games and their strategies are defined, including maze games, question-and-answer games, etc., which are used to evaluate the client's intentions and behaviors.

Game results and deviation establishment: Game results are used to establish the client's cognitive bias, behavioral bias, and intention bias, which serve as the basis for access authorization.

Access process and conditions:

Access request reception and processing: The system receives access requests from the client and requires the client to execute the specified game.

Access standards and verification: Access transactions are monitored through the blockchain to verify whether the game results meet the preset access conditions, so as to decide whether to grant access rights.

Dynamic access control and policy adjustment:

Access parameters and conversion values: The granting of access rights dynamically adjusts the conversion value of the access token based on multiple access parameters (such as client reputation and geographic location).

Deviation drift detection: Continuously monitor the client's game behavior deviations and detect deviation drift to identify potential security threats such as account takeover.

System architecture and components:

Main components: including processing circuits, memory, storage, and network interfaces, which work together to perform access control processes.

Trust agent and audit system: The trust agent is responsible for processing access requests and authorization decisions, and the audit system records all suspicious transactions.

Privacy protection and compliance:

Privacy protection: Protect the privacy of the client through blockchain technology to avoid directly exposing the client's identity information.

Compliance: Ensure that the solution complies with privacy regulations (such as GDPR) to avoid leaking user data.

Application scenarios and advantages:

Widely applicable: Applicable to a variety of protected entities, including servers, network devices, and cloud applications.

Efficient and scalable: Leverage the scalability of blockchain to provide efficient access control and flexible policy adjustments.

What is the main technical foundation proposed in, and how is it applied to network entity protection?

A: The main technical basis proposed is blockchain technology. Through the decentralized characteristics of the blockchain network and the transparency and immutability of transactions, it is applied to establish an access control system that does not require a third-party trust mechanism to protect network entities from malicious access.

How does the game mechanism mentioned in the patent work in the access authorization process?

A: The game mechanism is used to evaluate the client's intentions and behaviors. The client needs to perform a specified game before accessing the protected entity. The game results are used to establish the client's cognitive bias, behavioral bias, and intention bias, which serve as the basis for whether to grant access rights.

How is dynamic access control implemented, and what key factors does it involve?

A: Dynamic access control is achieved by dynamically adjusting the conversion value of the access token based on multiple access parameters (such as client reputation, geographic location, etc.). The system continuously monitors the client's game behavior deviations and detects deviation drift to identify potential security threats such as account takeover, thereby dynamically adjusting the access control strategy.

What roles do the trust agent and audit system play in the system architecture?

A: The trust agent is responsible for processing access requests and authorization decisions in the system, and decides whether to grant access rights based on the game results and preset access conditions. The audit system records all suspicious transactions to provide support for security analysis and compliance checks.

How does the proposed method balance privacy protection and compliance requirements?

Answer: The proposed method protects the privacy of the client through blockchain technology and avoids directly exposing the client's identity information, thereby complying with privacy protection regulations (such as GDPR). At the same time, the audit system records all transactions and ensures transparency to meet the needs of compliance checks.
