Abstract
This paper examines the theory of AES key scheduling and its potential problems. We propose a novel key scheduling scheme. The scheme improves the speed of key expansion without increasing computational complexity, reduces the dependency of output key on input key during key expansion, and improves the avalanche effect of key expansion.
