Well, as I've told before I don't know the internals of IL-2 and don't know if and how the suggestion is (realistically) appliable, but digitally signed executables and the likes are usually the way to go to assure file (executable or not) integrity and authenticity.
It seems to me the main problem lies in the fact that servers are out of control by online gamers, so they have to "trust" server administrators, and gamers PCs are out of central server control (not knowing how the tasks are assigned to servers and clients I have no idea about which part is the most critical).
In fact, in theory the "other side" could be even a fully "cloned" IL-2 server or client, without a single line of Oleg's code, just behaving the same way (except for cheats ... )!

In any case a direct integrity checking of the other side isn't possible, so you would have to rely on some form of secure remote checking, encrypted exchange of authentication messages between signed game modules and the like.
I'm not an expert but I suppose Oleg and his guys are skilled and smart enough to face also these issues, at least for BoB (and also to evaluate if it's worth the effort!).
