SecureRF’s Cryptographic Technology Employs Ground-Breaking Authentication, Data Protection, and Encryption and Decryption Security Protocols

The engine within the SecureRF security solutions is the ground-breaking, Algebraic Eraser™.  The Algebraic Eraser can be used to secure RFID tags, contactless payment systems, embedded systems or other low resource computing devices. This algorithm, which is thousands of times faster than other security protocols, supports a wide range of cryptographic functions:

• Authentication: Enables validation of an RFID tag and an RFID reader to confirm identity. Message authentication codes and digital signatures can be used to ensure data integrity against modification or forging.
• Data Protection: Secures the entire data stream that is being carried, including the commands and information.
• Encryption and Decryption: A type of data protection that employs the process of obscuring information to make it unreadable without special knowledge.  Encrypting the data on an RFID tag, with a key management protocol, allows trusted readers to read the data.
• Secured, Unencrypted Tag Data: Data on the RFID tag remains unencrypted, whilst a trust/policy layer maintains security—only transmitting it over a secured transport layer when in communication with cryptographically-authenticated trusted parties.
• Additional Security: Key agreement protocols, hash functions, and stream ciphers

SecureRF’s technology offers a combination of symmetric (secret-key) and asymmetric (public-key) cryptography that best achieves security, flexibility and scalability.

Our patent-pending Algebraic Eraser offers the first known linear-based security protocol—thousands of times faster than any other commercially available security method on the market today. Using industry-standard protocols and our proprietary technology, our secure solutions target passive and active RFID tags, and deliver the highest authentication, privacy, integrity, and non-repudiation available today.

The Algebraic Eraser system’s security is not feasibly reversible; and uniquely cloaks and then erases components of our process making it virtually impregnable. The algorithm runs in linear time with respect to the key length, and employs highly non-linear operations in a non-commutative infinite monoid—making for unprecedented security.
