Appearing in IEEE Information Theory Workshop (ITW) Paraty, Brazil, October, 2011.
This paper presents a stunning and counter-intuitive result --- that the encoding of k message symbols in an MDS code may require fewer than k-1 XOR operations per coding symbol. The result brings into question the lower bounds on the performance of encoding and decoding MDS erasure codes.
