Towards post-quantum symmetric cryptography

Abstract

Withthiswork, weintendondemonstratingtheneedfor improvements to the currently standardized AES family of cryptosystems, and provide a solution that meets the requirements of long-term security in the rapidly evolving threat landscape. The solution proposed is flexible, dramatically increases the potential security of the cipher, and strongly mitigates many of the most serious attacks on the AES family of cryptosystems. Further, our solution can be easily integrated into existing AES cryptosystem deployments, with only a few small changes required, thus preserving the large investments in this cipher both in hardware and software.
