Background/unmet need

Encryption, the process of encoding information so that only authorized parties may access it, is of paramount importance for secure communications in today’s world. Currently, there are several methods of encryption that are available for use. However, most of these methods require finite-length encryption keys (256-bits, 512-bits, 1024-bits) or provide fixed circuit designs, which may take some time to decrypt or encrypt.

Invention Description

Researchers at The University of Texas at Austin have developed a method that utilizes an "infinite" key and relies on software-reconfigurable hardware, which provides several layers of complexity that may render any attempt to crack the encryption key futile. Essentially, the software-reconfigurable hardware is capable of generating chaotic oscillator signals, which can then be used to encrypt the message using standard finite encryption key algorithms. Additionally, due to direct hardware implementation, this method allows for faster execution of encryption protocols than current methods of similar complexity.
