Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication control apparatuses face security issues due to the storage of confidential information, such as location information, which is necessary for dynamic frequency sharing, without proper encryption.
Innovation Solution
A communication control apparatus that receives encrypted information and performs secure computation to generate secondary communication parameters, ensuring confidentiality of primary communication system data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication control apparatus collects and stores information of primary communication systems to calculate interference, then the interference protection capability is improved, but the security risk increases due to storage of confidential information
Solution Approach 1:
The patent introduces an intermediary encryption mechanism between the communication control apparatus and primary communication system information. Instead of directly storing confidential information (location, identification), the system encrypts this data before storage and processing. The encryption acts as a mediator that allows the control apparatus to perform interference calculations while protecting the underlying confidential information from exposure.
2Object-affected harmful factors
If the communication control apparatus stores encrypted information of primary communication systems, then the security is improved, but the complexity of information processing increases
Solution Approach 1:
The patent applies preliminary encryption action to the primary communication system information before it is stored in the communication control apparatus. By encrypting the location information, identification information, and other confidential data in advance, the system reduces the complexity of ongoing security management. The encryption is performed once during information collection, and the encrypted form is then used for all subsequent interference protection operations without requiring continuous decryption/encryption cycles.

AI summary
Information related to a primary communication system acquired when a secondary communication service is used is concealed. A communication control apparatus includes a reception unit and a computation unit. The reception unit receives encrypted information related to primary communication in a primary communication system. The computation unit performs secure computation based on the encrypted information related to primary communication, and generates a secondary communication parameter being a communication parameter of a communication apparatus, the communication apparatus performing a secondary communication service being a communication service that uses at least a part of a frequency band of the primary communication system.
