Line 18: In 2006 at Cambridge University Kamil Kulesza published a paper "On inverting the VMPC one-way function", which investigated the issue but it left the problem open - the one-wayness of the function was neither proved nor denied. The VMPC ~~one-way~~ function is used in an [[encryption]] algorithm - the VMPC [[stream cipher]]. The algorithm is very efficient in software implementations (encrypt L bytes of plaintext do): <code>
