88-XOR Implementation of the AES MixColumns Matrix
Abstract
We give in this short note a circuit implementing the matrix-vector product with the 32x32 binary matrix of the AES MixColumns using 88 XOR gates. Previously known circuits minimizing this metric have been published in the past years and achieved 94 XOR, 92 XOR, 91 XOR, and 89 XOR. As far as we can tell, a circuit with 88 XOR was previously unknown.
