comment Simple RC4 key generation scheme
OK, so in the end I will use RC4-drop512, with my scheme of combining the master key and the nonce. The nonce will be sent in two steps: first unencrypted with the corresponding generated PRN stream used only to send the second nonce in an encrypted packet. Thanks everyone for your comments.

comment Simple RC4 key generation scheme
If I use the RC4-drop512 method you suggest, is there any difference, security-wise, whether I use the proposed scheme or just concatenate the master key and the Nonce?

@ D.W. So, what you are basically saying is that it is hard to analyze possible weaknesses of such a scheme and thus one should stick to something standard. I will definitely look into the recommended block ciphers. Thanks!

Just to avoid confusion - I am not trying to modify RC4's key scheduling algorithm but merely generate a new key to run the standard RC4's KSA on.
