There is no prove that VMPC is one-way function.
Line 6:
'''VMPC''' ("Variably Modified Permutation Composition") is [[encryption]] technology designed by Bartosz Zoltak, publicly presented in 2004 at an international [[cryptography]] conference Fast Software Encryption in [[Delhi, India]].
 
The core of the technology is the VMPC one-way function, applied in an encryption [[algorithm]] - the VMPC stream cipher.
