Wireless Secure Communication Using Plaintext Check Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially with advancements in VR and AR, the exposure of user data increases security risks due to the transmission of plaintext information, such as cell identifiers and activation paths, which can be exploited by unauthorized users to infer user movements and cause incorrect handovers.
Innovation Solution
Implementing a secure communication method where plaintext information is replaced by security check values, allowing the terminal device to verify the authenticity of received data using preconfigured correspondences or security checks, and ensuring consistent understanding through response information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plaintext information is transmitted in wireless communication systems, then communication efficiency is improved, but security risks increase due to data exposure
Solution Approach 1:
The patent introduces security check values as intermediary elements that replace plaintext information in communication messages. These security check values act as mediators between the transmitter and receiver, allowing the system to maintain communication efficiency while preventing direct exposure of sensitive plaintext data such as cell identifiers and activation paths.
Solution Approach 2:
The patent creates a correspondence relationship that copies the functionality of plaintext information through security check values. Instead of transmitting the actual plaintext, the system transmits security check values that can be mapped to the corresponding plaintext information through preconfigured correspondence tables, thereby maintaining data functionality while enhancing security.
2Object-affected harmful factors
If security check values are used to replace plaintext information, then security risks are reduced, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by preconfiguring correspondence relationships between security check values and plaintext information in the terminal device before actual communication occurs. This preconfiguration allows the device to automatically search and verify security check values during communication without requiring complex real-time processing, thereby reducing the operational complexity despite the enhanced security mechanism.
3Speed
If plaintext information is transmitted, then data transmission speed is improved, but user privacy is compromised
Solution Approach 1:
The patent uses security check values as intermediary elements that maintain the speed of data transmission while protecting user privacy. These intermediaries allow fast communication by avoiding the overhead of encryption/decryption operations while still preventing unauthorized access to sensitive information such as user movement patterns and cell identifiers.

AI summary
Embodiments of this application provide a secure communication method. In the method, security check is introduced in a plaintext information transmission process. An access network device preconfigures a security check value or a correspondence between a security check value and plaintext information, and performs security check in subsequent communication, to reduce security risks caused by user data exposure.
