Secure RFID Tags Actively Authenticate and Encrypt Communications

SecureRF Corporation has its own line of secure radio frequency identification (RFID) tags featuring the Algebraic Eraser™ security protocol to actively authenticate and encrypt reader-tag communications.  The first, known as the LIME Tag™, is a battery-assisted passive (BAP) RFID tag with Onboard Security™ and optional sensors that meets EPCglobal Class 1, Gen 2 standards.  A secure passive UHF RFID tag is currently under development.

LIME Tag - Our RFID Solution with Onboard Security

The LIME Tag (for LIghtweight, Multistream Encryption) provides data authentication at the RFID reader, RFID tag, and data level. This prevents unauthorized reading of the private information, provides anonymity and guards consumer privacy e.g. HIPAA.

Data protection and encryption features prevent tampering of the data and makes the LIME Tags untraceable and non-cloneable. The LIME Tag uses unique session keys and a self-contained public key (asymmetric) engine.

In addition to providing Onboard Security functions, the LIME Tag has other unique features:

• The LIME Tag with optional sensors enables temperature tracking, tamper indication, shock sensing and other functions.
• An extended user memory that stores up to 4Mbits of data.
• A long read/write range of up to 150 feet/50 meters.

Universal Standards Facilitate Wireless Implementation

SecureRF tags support a wide range of wireless standards, including EPCglobal Class 1 Generation 2, the same UHF standards used in ISO specification 18000-6C.  These global standards provide the foundation for future RFID products used in asset tracking and identification for supply chain and related applications. 

These fully secure RFID solutions operate with currently installed EPCglobal Class 1, Gen 2 readers without the need for firmware upgrades; a significant implementation advantage.
