Technology> Radio Frequency Identification

SecureRF’s foundational Algebraic Eraser™ addresses the critical security needs of the radio frequency identification (RFID) industry and can be implemented in:

• Passive RFID tags (These do not have batteries and are powered by reflecting back radio waves from the reader.)
• Battery–assisted passive RFID tags, also known as semi-active tags (They communicate using the same backscatter technique as passive tags and use a battery to run the circuitry on the microchip or an onboard sensor.)
• Active RFID tags (They use a transmitter, powered by a battery or other source, to send back information to the reader.)

A secure RFID solution includes these components:

• RFID tags with the SecureRF’s Algebraic Eraser security protocol and optional sensors
• EPCglobal Class 1, Gen2 compliant readers 
• SecureRF’s interface between the readers and the business network, called the Secure Reader Host

This architecture provides a secure link over an open channel while providing strict compliance with the EPCglobal Class 1, Gen 2 UHF transport protocol.  Certificates protect the business management process, and strong PKI provides privacy protection.

SecureRF has incorporated the Algebraic Eraser technology into our own secure RFID tags and RFID tags with sensors.
