Zero Latency Gateway for IoT Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with low processing power and small memory capacity, commonly used in IoT systems, are vulnerable to attacks due to their inability to securely configure and communicate, as they lack the resources to determine authorized data packets, leading to potential malicious interference.
Innovation Solution
A node device is introduced between the transmitter and receiver to monitor data packets, parse them before receipt, and determine authorization by checking source data, pre-defined whitelists, and cryptographic tokens, distorting or discarding unauthorized packets to prevent malicious actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic verification is implemented at the receiver device, then security is improved, but processing requirements and memory capacity exceed the capabilities of low-power IoT devices
Solution Approach 1:
A gateway device is introduced as an intermediary between the transmitter and receiver. The gateway performs cryptographic verification and data packet filtering on behalf of the resource-constrained receiver device, allowing the receiver to maintain low power consumption while still benefiting from security verification through the intermediary gateway
2Reliability
If data packet filtering is performed at the receiver device, then security is improved, but processing time and energy consumption increase beyond acceptable limits for low-power devices
Solution Approach 1:
The gateway device performs data packet filtering and verification in advance before packets reach the receiver. By conducting security checks preliminarily at the gateway, the receiver device avoids the energy-consuming task of processing and analyzing each incoming packet, thus reducing its energy consumption while maintaining security
3Ease of operation
If configuration capabilities are added to low-power devices, then ease of configuration is improved, but device complexity and power consumption increase
Solution Approach 1:
The gateway serves as a configuration intermediary that manages and distributes configuration data to multiple receiver devices. This allows receiver devices to remain simple and low-power while still benefiting from centralized configuration management through the gateway, avoiding the need for complex local configuration capabilities

AI summary
Broadly speaking, embodiments of the present technique provide apparatus, systems and methods to enable secure communication between devices. In particular, the present techniques provide an apparatus configured to monitor for a data packet transmitted between a transmitter and a receiver, determine if the data packet is permitted to be transmitted, and act on at least part of the data packet to prevent the receiver from acting on the data packet if it is not permitted to be transmitted. In other words, the present techniques provide/implement security filters in a communication channel between a transmitter and a receiver to reduce the risk that unauthorised data packets are sent to, and implemented by, the receiver device.
