Method for blockchain digital signature service

Architecture of electronic device:

Device composition: including communication circuit, display, memory and at least one processor, the processor can run normal OS and secure OS at the same time.

Memory function: store instructions, when executed, the processor controls the device to receive, process and transmit digital signature requests related to blockchain.

Digital signature service process:

Receive request: receive digital signature request message of blockchain through communication circuit in normal OS.

Drive management software: drive blockchain management software in response to request, and transmit signature request message to secure OS through the software.

User authentication: in secure OS, configure user authentication request screen based on trusted application and output to display.

Create signature: in secure OS, create digital signature according to private key stored in memory.

Transmit signature message: transmit digital signature message back to application in normal OS through blockchain management software.

Isolation of secure OS and normal OS:

Isolated operation: secure OS and normal OS run separately on processor, secure OS uses independent resources and cannot be accessed by unauthorized programs or applications.

Private key storage: Private keys are stored in an encrypted environment of a secure OS to ensure the security of private keys.

User authentication and signature creation:

Multiple authentication methods: The user authentication request screen supports multiple authentication methods, such as passwords, fingerprints, and facial recognition.

Digital signature algorithm: Use secure algorithms such as elliptic curve cryptography to create digital signatures to ensure the validity and security of signatures.

Role of blockchain management software:

Software functions: Responsible for transmitting messages between normal OS and secure OS, and managing blockchain-related applications and data.

Interactive interface: Provides an interactive interface with trusted applications, and supports the creation and verification of digital signatures in a secure environment.

Enhanced security and reliability:

Host information request: Request the host information of the service during the digital signature process, and provide it to the user for verification together with the signature request information.

Phased authentication: The user authentication request screen can be configured in stages, first verifying the host information, and then requesting the user to enter personal authentication information.

Application scenarios and advantages:

Application scenarios: Applicable to digital signature services in blockchain networks, especially in the fields of electronic transactions, digital currency management, etc.

Advantages: It provides higher security and reliability. Through the secure storage of private keys and multiple authentication methods of users, it effectively prevents private key leakage and digital signature forgery.

The following are the answers to the short-answer questions sorted according to the content of the file:

What are the main parts of the architecture of electronic devices?

Electronic devices mainly include communication circuits, displays, memory and at least one processor. The processor can run the normal operating system (Normal OS) and the secure operating system (Secure OS) at the same time.

What is the basic process of digital signature service?

The basic process of digital signature service includes: receiving the digital signature request message of the blockchain in the normal OS; driving the blockchain management software and transmitting the signature request message to the secure OS; configuring the user authentication request screen in the secure OS and outputting it to the display; after the user authenticates, creating a digital signature based on the private key in the secure OS; and finally transmitting the digital signature message back to the application in the normal OS.

How is the secure OS isolated from the normal OS, and what impact does this have on security?

The secure OS runs separately from the normal OS on the processor, uses independent resources, and cannot be accessed by unauthorized programs or applications. This isolation ensures the secure storage of sensitive information such as private keys, and prevents external attacks and internal leaks.

What optional authentication methods are available to users when performing digital signature authentication?

When performing digital signature authentication, users can use multiple authentication methods, including passwords, fingerprints, facial recognition, iris recognition, etc. These multiple authentication methods improve the security of authentication and reduce the risk of illegal access.

What role does blockchain management software play in digital signature services?

In digital signature services, blockchain management software is responsible for transmitting messages between normal OS and secure OS, and managing blockchain-related applications and data. It also provides an interactive interface with trusted applications, and supports the creation and verification of digital signatures in a secure environment.

How does 543x.com enhance the security and reliability of the digital signature process?

543x.com enhances the security and reliability of the digital signature process by requesting the host information of the service and providing it to the user for verification during the signing process, as well as adopting a staged user authentication request screen (first verifying the host information, and then requesting the user to enter personal authentication information). In addition, the encrypted storage of private keys in secure OS also ensures the security of private keys.

What are the main application scenarios of this digital signature service?

The main application scenarios of this digital signature service include electronic transactions in blockchain networks, digital currency management and other fields. It provides higher security and reliability and is suitable for environments that require strict security control.
