Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing devices face security challenges due to their limited computational power and memory, making them vulnerable to unauthorized access, eavesdropping, and replay attacks, as they use open standard-based interfaces for wireless communication.
Innovation Solution
A hearing device with a processing unit, memory unit, and interface that receives connection requests, obtains session identifiers, and verifies client device data using selected keys to authenticate and secure communication, minimizing computational overhead and power consumption while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hearing device uses open standard-based interfaces for wireless communication, then ease of operation and adaptability are improved, but security and reliability deteriorate due to vulnerability to unauthorized access and attacks
Solution Approach 1:
The patent implements preliminary authentication actions before establishing communication sessions. The hearing device performs authentication of incoming connection requests and verifies client device data before allowing any data transmission or memory access, preventing unauthorized access in advance
Solution Approach 2:
The patent introduces authentication protocols and verification mechanisms as intermediary layers between the open wireless interface and the hearing device's internal systems. These intermediaries validate connection requests and filter authenticated data, allowing open communication while maintaining security
2Reliability
If advanced security algorithms and protocols are implemented in a hearing device, then security and reliability are improved, but device complexity and computational requirements worsen
Solution Approach 1:
The patent implements partial authentication mechanisms tailored to the specific security needs of hearing devices. Rather than implementing complete advanced security suites, the device performs selective authentication checks and verification steps that provide adequate security without requiring full computational capabilities of advanced algorithms
Solution Approach 2:
The authentication system is designed to operate autonomously within the hearing device's constrained environment. The device independently verifies connection requests and authenticates communication partners using pre-configured authentication data, eliminating the need for external authentication servers or complex computational resources
3Reliability
If authentication and verification processes are performed for every connection request, then security is improved, but power consumption and processing time worsen
Solution Approach 1:
The patent implements optimized authentication processes that quickly verify connection requests when possible. The system performs rapid authentication checks for trusted devices and uses streamlined verification paths for common communication scenarios, reducing the time and energy required for security operations
