Digital Certificate Security Channel Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital certificate management methods over wireless local area networks transmit messages in plaintext, ensuring only data integrity but not authenticity or confidentiality, leading to insecure data transmission.
Innovation Solution
Establishing a security data channel between digital certificate requesting and issuing devices using an authorization code to generate a security key for encrypting messages, ensuring secure data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are transmitted in plaintext between digital certificate requesting device and issuing device, then data integrity can be verified, but data authenticity and confidentiality cannot be ensured
Solution Approach 1:
The patent applies preliminary action by establishing a security data channel and generating encryption keys before transmitting digital certificate management messages. The requesting device and issuing device negotiate security parameters and set up encrypted communication channels in advance, so that when actual certificate management messages are transmitted, they are already protected by encryption, thus ensuring both integrity and confidentiality from the outset.
Solution Approach 2:
The patent changes the transmission parameter of messages from plaintext to encrypted format. By introducing encryption algorithms and transforming the message format from unencrypted to encrypted, the system maintains data integrity verification while adding layers of protection for authenticity and confidentiality. The message structure includes both the original data and encryption verification elements.
2Ease of operation
If messages are transmitted in plaintext over network, then communication simplicity is maintained, but security protection is insufficient
Solution Approach 1:
The patent introduces an intermediary security mechanism between the requesting device and issuing device. A security data channel is established as an intermediate layer that handles encryption and decryption operations. This intermediary layer transparently protects messages during transmission without requiring changes to the underlying communication protocol or increasing operational complexity for the users.
3Object-affected harmful factors
If security data channel with encryption is established, then data authenticity and confidentiality are protected, but system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the requesting device and issuing device to autonomously negotiate security parameters and establish encrypted communication channels without requiring external security infrastructure or manual configuration. The devices automatically generate encryption keys, select encryption algorithms, and manage the security data channel setup process, reducing the need for complex external security systems.
Data Source
AI summary
A method and device for managing a digital certificate are provided. A digital certificate requesting device negotiates with a digital certificate issuing device by using an acquired authorization code, to establish a security data channel and generate a security key, and messages can be encrypted with the generated data communication key during a process of message interaction between the digital certificate requesting device and the digital certificate issuing device, thereby effectively increasing the security in data transmission. The method and device are applicable for automatically requesting for, querying, updating, revoking a digital certificate and acquiring a digital certificate revocation list in various scenarios.
