Original sentence: In 2006 at Cambridge University, Kamil Kulesza investigated the problem of inverting VMPC and concluded "results indicate that VMPC is not a good candidate for a cryptographic one-way function".The VMPC function is used in an encryption algorithm - the VMPC stream cipher.The function was designed such that inverting it, i.Where 256-element permutation P and integer value s are obtained from the encryption password using the VMPC-KSA (Key Scheduling Algorithm).obtaining f from g, would be a complex problem
Edited sentence: In 2006 at Cambridge University Kamil Kulesza published a paper that investigates the problem of inverting VMPC.Inverting the function, i.The VMPC  function is used in an encryption algorithm - the VMPC stream cipher.The paper concluded that "results indicate that VMPC is not a good candidate for a cryptographic one-way function".Theoretically speaking - if these results were possible to be proved - it would imply that VMPC is a true one way function, which would solve the famous P vs NP problem.Where 256-element permutation P and integer value s are obtained from the encryption password using the VMPC-KSA (Key Scheduling Algorithm), which can be found at the VMPC Homepage along with the VMPC-MAC (Message Authentication Code) allowing to authenticate messages encrypted with the VMPC Stream Cipher.obtaining f from g appears to be a complex problem
