IoT Payment Gateway Mutual Authentication for Secure Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices lack secure communication protocols for proximity payments, leading to vulnerabilities from malicious devices masquerading as legitimate ones, and there are no standardized methods for secure transactions between IoT devices.
Innovation Solution
Implement a mutual authentication mechanism using key certificates and keys for secure communication between IoT devices, with a trusted execution environment and a secure payment gateway to manage device identities and secure payment data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IoT devices use existing communication protocols for proximity payments, then device compatibility and ease of operation are improved, but security is worsened due to vulnerabilities from malicious devices masquerading as legitimate ones
Solution Approach 1:
The patent introduces a gateway as an intermediary component that mediates communication between IoT devices and payment networks. The gateway implements mutual authentication mechanisms and secure protocol handling, preventing malicious devices from directly compromising the payment system while maintaining compatibility with existing IoT communication protocols.
Solution Approach 2:
The patent implements preliminary authentication and device verification steps before allowing payment transactions. The mutual authentication mechanism verifies device identities and establishes secure communication channels in advance, preventing malicious devices from masquerading as legitimate ones during actual payment operations.
2Reliability
If IoT devices implement mutual authentication with key certificates and keys, then communication security is improved, but device complexity increases
Solution Approach 1:
The gateway serves as a centralized authority that manages key certificates and authentication credentials. By offloading the complex key management and certificate verification tasks to the gateway, individual IoT devices can implement mutual authentication with reduced complexity, as the gateway handles the heavy computational and storage requirements for security credentials.
3Reliability
If a secure payment gateway is implemented to manage device identities, then transaction security is improved, but system complexity increases
Solution Approach 1:
The payment gateway is designed as a multi-functional component that handles device registration, identity management, mutual authentication, and payment transaction processing. By consolidating these security-critical functions into a single universal gateway, the system achieves high transaction security without distributing complexity across multiple specialized components.
Data Source
AI summary
Systems and methods for secure communication of data packets are described using a communications gateway and protocol. One or more payment generator devices utilize trusted execution environments to store identity attestation parameters which are then utilized during registration and/or validation of device identity at the gateway for secure transmission of secure data, including, for example, payment data.
