Beacon MIC Authentication for Low-Signaling IoT Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication process between a station (STA) and an access point (AP) involves complex signaling processes, leading to low efficiency and inefficiency in data interaction, particularly for ambient power-enabled IoT devices that require frequent association and authentication procedures.
Innovation Solution
A communication method involving the transmission and reception of beacon frames with Message Integrity Codes (MICs) to authenticate devices, reducing the need for extensive signaling procedures and enhancing communication efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional signaling processes (scanning, authentication, association, key generation) are performed before each data interaction, then transmission reliability is ensured, but communication efficiency deteriorates
Solution Approach 1:
The patent performs authentication, association, and key generation procedures in advance during the scanning phase, so that when data interaction is needed, the devices are already connected and authenticated. This preliminary action eliminates the need to repeat these signaling processes before each data transfer, thereby improving communication efficiency while maintaining transmission reliability
Solution Approach 2:
The patent combines multiple signaling processes (scanning, authentication, association, and key generation) into a single integrated procedure. By merging these previously separate steps into one unified process, the total signaling overhead is reduced, and devices can enter data interaction mode more quickly without sacrificing security or reliability
2Reliability
If complex signaling processes are performed frequently, then transmission security is maintained, but energy consumption increases
Solution Approach 1:
The patent performs energy-intensive authentication, association, and key generation procedures once in advance during scanning, rather than repeatedly executing them before each data interaction. This preliminary action significantly reduces the energy consumption for ambient power-enabled IoT devices while maintaining transmission security through the pre-established secure connection
3Reliability
If traditional authentication and association procedures are performed before each data interaction, then transmission reliability is ensured, but communication process complexity increases
Solution Approach 1:
The patent completes authentication, association, and key generation in advance during the scanning phase, so that the complex signaling processes are performed only once rather than repeatedly before each data interaction. This reduces the perceived complexity of the communication process while maintaining transmission reliability through the pre-established secure connection
Solution Approach 2:
The patent extracts the complex authentication and association procedures from the data interaction process itself and places them in a separate preliminary scanning phase. This separation removes the complexity burden from the main data communication flow, making the overall process simpler while preserving reliability

AI summary
A communication method and a communication device. In the method, a first device sends a beacon frame to a second device, and receives a first frame sent by the second device, the first frame carries a first message integrity code (MIC), and the first MIC is used for the first device to verify the legitimacy of the second device.
