Hi,

anyone knows why the decryption function of DES is the same as the encryption function exept the key order?

I have to find the response (mathematical) of this question. I have looked in Handbook of Applied Cryptography, Applied Cryptography,Cryptography theory and practice and the Internet but i hav'nt found the response.

Thanks in advance
