Communication Parameter Sharing and Invalidation for Wireless Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies allow multiple devices to acquire the same wireless parameter, leading to unauthorized access and security issues in wireless communication networks.
Innovation Solution
A communication apparatus and method that shares a communication parameter with an external device, but puts the parameter in a state where it cannot be shared further once communication is initiated, preventing other devices from acquiring the same parameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a communication parameter is shared with an external apparatus to enable wireless communication, then ease of connection establishment is improved, but security deteriorates because multiple apparatuses can acquire the same parameter and join the wireless network
Solution Approach 1:
The system performs preliminary actions by establishing communication through first communication means before sharing parameters, and invalidates the shared parameter after second communication means is activated. This preliminary sequence ensures that parameter sharing occurs only after initial authentication, preventing unauthorized access while maintaining ease of connection for authenticated devices.
Solution Approach 2:
The communication parameter dynamically changes state from shareable to non-shareable based on communication progress. Initially, the parameter is shared to enable easy connection establishment. Once second communication means successfully communicates using this parameter, the system automatically invalidates it, making it non-shareable. This dynamic state transition resolves the contradiction between ease of operation and security.
2Ease of operation
If the same communication parameter is used for wireless communication, then compatibility and ease of operation are improved, but reliability deteriorates due to potential unauthorized joining by other apparatuses
Solution Approach 1:
The system performs preliminary authentication through first communication means before enabling parameter sharing for second communication means. This preliminary step ensures that only authenticated apparatuses can acquire and use the communication parameter, maintaining both ease of operation for authorized devices and reliability by preventing unauthorized joining.
Solution Approach 2:
The system discards (invalidates) the communication parameter after it has been successfully used to establish second communication means. This discarding action ensures that the parameter cannot be reused by other apparatuses, thereby maintaining reliability while having previously enabled ease of operation for the authenticated connection.

AI summary
There is provided a communication apparatus having a first communication unit configured to hold a first communication parameter and share the held first communication parameter with an external apparatus, and a second communication unit configured to perform communication with the external apparatus by using the first communication parameter that the first communication unit shares with the external apparatus. A control unit performs control so that communication by the second communication unit is started in response to sharing of the first communication parameter by the first communication unit. When communication by the second communication unit is to be performed in response to sharing of the first communication parameter by the first communication unit, the control unit puts the first communication parameter, which has been shared with the external apparatus, in a state in which it cannot be shared via the first communication unit.
