Title:
Towards Post-Quantum Secure Symmetric Cryptography: A Mathematical Perspective
Authors: Xenia Bogomolec, John Gregory Underhill, Stiepan Aurélien Kovac
Abstract:We introduce an independent research project on symmetric cryptography with a focus on foreseeable industrial needs and higher post-quantum security compared to currently used symmetric algorithms. It was initiated by the independent IT-Security experts Kovac and Underhill. The result is the new symmetric cryptographic algorithm eAES, which is intended to be a stronger brother of the widely used Advanced Encryption Standard, the standardized version of the Rijndael algorithm. In this analysis we show, that eAES offers an enhanced complexity by a factor ≥ 2^126 regarding the quantum cryptanalysis Grover’s search algorithm compared to AES for 256 bit keys. Furthermore we outline the basic facts and open questions regarding quantum algebraic attacks on eAES.
