MultiSwap

In cryptography, MultiSwap is a block cipher/MAC created by Microsoft in 1999 as part of its Windows Media DRM service (WMDRM). Microsoft's internal name for the algorithm is not publicly known; it was dubbed MultiSwap in a 2001 report on WMDRM under the pseudonym "Beale Screamer". Borisov, et al. applied a multiplicative form of differential cryptanalysis to break MultiSwap.
