Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication networks face challenges in balancing overhead information with payload information, leading to reduced throughput rates and increased processing complexity due to the need for additional mechanisms to control and secure data transmission.
Innovation Solution
An integrated security mechanism that uses a single integrated information unit identifier to encrypt data, combining transmission control and security functions within a single protocol layer, reducing overhead and processing requirements by integrating sequence numbers and nonce information into a single header field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional mechanisms are provided for controlling communication of payload information, then improved accuracy of communication is achieved, but throughput rates decrease and processing complexity increases
Solution Approach 1:
The patent combines transmission control functions (sequence numbers) and security functions (nonce values) into a single integrated header structure. This merging eliminates the need for separate overhead fields for each function, reducing total overhead information while maintaining both communication accuracy and throughput rates.
Solution Approach 2:
The integrated header field serves multiple functions simultaneously: it provides sequence numbering for transmission control, nonce values for security/encryption, and identification for packet tracking. This multi-functionality reduces the number of separate mechanisms needed, thereby improving throughput while maintaining reliability.
2Reliability
If additional mechanisms are provided for controlling communication of payload information, then improved accuracy of communication is achieved, but device complexity increases
Solution Approach 1:
The patent merges sequence number generation, nonce value generation, and packet identification into a single integrated header structure. This consolidation reduces the number of separate processing components needed at both transmitting and receiving ends, thereby reducing device complexity while maintaining communication accuracy.
Solution Approach 2:
The integrated header field performs multiple functions (transmission control, security, identification) simultaneously, eliminating the need for separate processing logic for each function. This reduces the sophistication and complexity of processing components required in communication devices.
3Reliability
If overhead information is increased to improve communication control, then communication accuracy is improved, but payload information transmission efficiency decreases
Solution Approach 1:
The patent combines multiple overhead information elements (sequence numbers, nonce values, identification fields) into a single integrated header structure. This merging reduces the total amount of overhead information transmitted, thereby increasing the proportion of payload information in each transmission unit and improving payload transmission efficiency while maintaining communication control.
Solution Approach 2:
The integrated header field provides multiple control functions (transmission control, security, identification) within a single compact structure, reducing the overhead required for each function individually and improving overall payload transmission efficiency.

AI summary
An unencrypted media access control layer (MAC) protocol data unit (MPDU) having a header is received at a wireless network interface device. The header includes a sequence number. The wireless network interface device uses the sequence number to encrypt data in the unencrypted MPDU to generate an encrypted MPDU, and transmits the encrypted MPDU.
