Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of implementing secure and scalable communications for Internet of Things (IoT) devices, particularly in scenarios with limited memory or RAM resources, is exacerbated by the increased prevalence of IoT connections, leading to security and privacy breaches.
Innovation Solution
Establishing an IoT protocol-based machine-to-machine communication channel with a secure off-the-record (OTR) communication session using cryptographic protocols like AES symmetric-key algorithm, Diffie-Hellman key exchange, and malleable encryption, ensuring encrypted communications without logging or recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic protocols are implemented for secure communications, then security and privacy are improved, but device complexity and resource consumption increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary that performs cryptographic operations and key management. This mediator handles the complexity of secure communications externally, allowing resource-constrained IoT devices to benefit from encryption without bearing the full computational burden, thus resolving the contradiction between security and device complexity
Solution Approach 2:
The patent extracts the heavy cryptographic processing functions from the IoT devices themselves and relocates them to the gateway server. This extraction removes the burden of complex cryptographic implementations from constrained devices, enabling secure communications while reducing device complexity requirements
2Reliability
If cryptographic protocols are implemented for secure communications, then security and privacy are improved, but memory and processing resources are consumed
Solution Approach 1:
The gateway acts as an intermediary that performs energy-intensive cryptographic operations centrally rather than distributing them across multiple resource-constrained IoT devices. This concentrates the energy consumption in a single location with adequate resources, allowing individual devices to maintain security with minimal energy expenditure
Solution Approach 2:
The patent extracts cryptographic processing functions from IoT devices and relocates them to the gateway server. This extraction removes the energy burden of cryptographic operations from devices with limited power resources, enabling secure communications while preserving device energy for other critical functions
3Device complexity
If traditional communication protocols are used, then device complexity is reduced, but security and privacy protection is insufficient
Solution Approach 1:
The gateway serves as a protective intermediary that implements security measures between IoT devices and the network. This mediator handles authentication, encryption, and threat detection, protecting devices from security breaches while allowing them to use simpler communication protocols without directly exposing them to network threats

AI summary
Novel tools and techniques might provide for implementing secure communications for IoT devices. In various embodiments, a gateway or computing device might provide connectivity between or amongst two or more Internet of Things (“IoT”) capable devices, by establishing an IoT protocol-based, autonomous machine-to-machine communication channel amongst the two or more IoT capable devices. For sensitive and/or private communications, the gateway or computing device might establish a secure off-the-record (“OTR”) communication session within the IoT protocol-based, autonomous machine-to-machine channel, thereby providing encrypted machine-to-machine communications amongst the two or more IoT capable devices, without any content of communications that are exchanged amongst the IoT capable devices over the secure OTR communication session being recorded or logged. In some cases, the secure OTR communication session utilizes cryptographic protocols including, without limitation, one or more of AES symmetric-key algorithm, Diffie-Hellman key exchange, SHA-1 hash function, forward secrecy, deniable authentication, malleable encryption, and/or the like.
