Wireless Network Integrity Protection for Management Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks lack effective integrity protection for management and control traffic, making them susceptible to security threats such as denial of service and forgery attacks, which can compromise data integrity and confidentiality.
Innovation Solution
The implementation of an integrity protection system that generates pairwise integrity keys to secure management and control traffic, using a communication interface with an integrity protection generator and encryptor to encrypt data and provide message integrity codes, ensuring the authenticity and integrity of communication frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication networks transmit management and control traffic without integrity protection, then communication simplicity and transmission speed are maintained, but security is compromised making the network susceptible to denial of service, forgery attacks, and unauthenticated messages
Solution Approach 1:
The patent applies preliminary action by generating pairwise integrity keys and computing message integrity codes (MICs) before transmitting management and control frames. The integrity protection generator creates cryptographic protection in advance, allowing receiving devices to verify authenticity without adding complex real-time verification mechanisms. This pre-computation approach ensures data integrity while maintaining relatively simple device architecture.
2Reliability
If authentication of management and control traffic is implemented to provide data integrity and confidentiality, then security is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent uses message integrity codes (MICs) as an intermediary mechanism between transmitting and receiving devices. The MIC acts as a cryptographic mediator that provides authentication without requiring complex mutual verification protocols. The integrity protection generator creates MICs that can be independently verified by receiving devices, simplifying the authentication system while ensuring reliable verification of management and control frames.
3Reliability
If no integrity protection is used for wireless communication, then energy consumption and processing time are reduced, but the network becomes vulnerable to security threats
Solution Approach 1:
The patent applies parameter changes by selectively applying integrity protection only to management and control frames rather than all data traffic. This selective approach changes the protection parameter from universal to targeted, reducing overall energy consumption while providing necessary security for critical control traffic. The system dynamically adjusts protection levels based on frame type, optimizing energy efficiency while maintaining security for authenticated user communications.
