Key Transformation Approach for Rijndael Security
Published 2008“…This method improves the security of Rijndael Key Scheduling by increasing the bit confusion and diffusion of the Rijndael Subkey. The new method has shown positive results in terms of the bit confusion and diffusion of Subkey and it has increased bit confusion and diffusion compared to the Subkey of the original Rijndael Key Schedule.…”

Key transformation approach for Rijndael security.
Published 2010“…Thus, a new transformation method which is called Shiftrow is proposed into the 128-bit Rijndael Key Schedule based upon information principles (bit confusion and diffusion properties). The new method has shown positive results in terms of the bit confusion and diffusion of subkey and it has increased bit confusion and diffusion compared to the subkey of the original Rijndael key schedule.…”
