IoT Authentication Credential Distribution Across Frequency Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT networks face significant security and privacy concerns due to the lack of standardization and vulnerabilities in existing technologies, which hinder their adoption as users fear the confidentiality, authenticity, and integrity of data being exchanged by machines, as exemplified by high-profile hacking incidents like the Las Vegas casino aquarium thermometer hack.
Innovation Solution
A network security system utilizing transceivers with multiple antennas in a MIMO configuration, capable of sending and receiving data over multiple frequencies, parses and compiles authentication credentials across different frequency channels, ensuring secure authentication and data transmission through a processor that reconstructs credentials on multiple antennas, enhancing security by distributing authentication across various frequency channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication credentials are transmitted over a single frequency channel, then the transmission process is simple and fast, but the security is vulnerable to hacking and interception
Solution Approach 1:
The authentication credential is divided into multiple portions, with each portion transmitted over a different frequency channel. This segmentation ensures that even if one channel is compromised, the complete credential remains secure, directly resolving the vulnerability to hacking while maintaining manageable system complexity through modular transmission.
Solution Approach 2:
The patent introduces frequency diversity as an additional dimension for credential transmission. Instead of relying solely on a single communication channel, the system distributes credential portions across multiple frequency channels, adding a dimensional layer of security that protects against interception without significantly increasing operational complexity.
2Reliability
If multiple frequency channels are used for transmitting credential portions, then security is enhanced, but the authentication process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary actions by pre-establishing the mapping between credential portions and frequency channels before authentication begins. This preparation allows the actual authentication process to proceed efficiently, as the receiver already knows which portions to expect on which channels, reducing the time penalty associated with multi-channel transmission.
Solution Approach 2:
The patent implements mechanisms to rapidly transmit and reassemble credential portions across multiple channels. By optimizing the transmission process to move quickly through each channel and efficiently reassemble the portions at the receiver, the system minimizes the time loss while maintaining the security benefits of multi-channel distribution.
3Reliability
If credential portions are distributed across multiple frequency channels, then security against interception is improved, but the risk of loss or corruption of portions increases
Solution Approach 1:
The system implements feedback mechanisms where the receiver verifies the successful reception and integrity of credential portions from each frequency channel. If a portion is lost or corrupted during transmission, the feedback system detects this and triggers appropriate error handling or retransmission protocols, ensuring that the distributed credential structure does not compromise overall integrity.
Data Source
AI summary
A transmitter in an Internet of Things (IoT) network parses an authentication credential into different portions and assigns each portion to one of multiple pre-determined frequency channels for transmission. A receiver for which the authentication credential is intended first authenticates that the different portions of the authentication credential are sent on the pre-determined frequency channels. The receiver then compiles the portions and authenticates the authentication credential.
