NFC Dynamic Tags for Secure Wireless Node Pairing ID: 2013-016

A novel method for secure and cost-effective pairing of lightweight wireless nodes using NFC Dynamic Tags.

Technology Overview

This technology introduces a new approach for pairing lightweight wireless nodes securely and inexpensively using Near-Field Communication (NFC) Dynamic Tags. By overcoming the limitations of pre-installed cryptographic keys, this method facilitates dynamic growth and repurposing of nodes within networks. It is distinguished by its use of NFC Dynamic Tags for data exchange, eliminating the need for pre-installed keys and thereby reducing both costs and user errors commonly associated with traditional pairing methods.

Key Advantages

• Eliminates the need for pre-installed cryptographic keys, facilitating dynamic network growth
• Reduces costs by requiring only one NFC reader per network
• Minimizes user errors associated with traditional pairing methods
• Enhances security by using dynamic tags over static ones, preventing unauthorized access
• Supports the repurposing of nodes without compromising security

Problems Addressed

• High costs and complexity associated with traditional node pairing methods
• Security vulnerabilities due to static NFC tags and pre-installed cryptographic keys
• Limitations in network growth and node repurposing
• User errors during the pairing process

Market Applications

• Secure wireless networks in smart homes and Io
• T devices
• Healthcare monitoring systems requiring secure data transmission
• Industrial automation and control systems
• Consumer electronics that require secure, easy-to-setup wireless connections
• Secure key distribution for lightweight wireless networks
