With this technique, the team is said to have developed the world's most efficient Advanced Encryption Standard (AES) cryptographic processing circuit, with an energy consumption reduced by more than 50%.
As a result it may now be possible to include encryption technology in information and communication technology devices that have tight energy constraints, in particular enhancing the safety of next-generation IoT devices.
This technique see the AES encryption algorithm represented as a calculation based on a special numbering system called a Galois field. The research group has transformed the input numerical representation and is now able to perform multiple computations in one go. Using this method, the number of required circuit elements can be reduced significantly.
The AES cryptographic circuit is said to be suited to global communication standards such as SSL and TLS.
