SecureRF May Have The Holy Grail For Encryption

SecureRF has a secret that it wants everyone to know about. It is a new encryption technology that has an interesting property. It can be applied in linear time. Doesn't sound like much, but it is, especially when compared to conventional encryption technology that operates in quadratic time.

Assuming the encryption algorithm can stand up to scrutiny, this will have a major impact across the computing spectrum. Unlike other algorithms, this one can be implemented efficiently in software on 8-bit microcontrollers. Likewise, a hardware implementation is so small that it is comparable to a typical microcontroller peripheral. This is why the technology is well suited for the initial target application: secure RFID tags.

SecureRF's approach supports public key encryption methodologies making it an interesting replacement for other, well established algorithms. The technology is already available, but it will take some time for third party verification like that applied to other algorithms. The biggest hurdle for testers will be the change in technology, since it uses an approach that is different from the multiplication of large prime numbers used with algorithms such as RSA. This is definitely rocket science in scope, and it will be interesting to see how it takes off.
