I read a sentence from a book.
Clearly that should not render an encryption scheme insecure, and so any viable definition must somehow rule out such behavior as being a successful attack.
Among these clauses, I am confused by the last clause "any viable definition must somehow rule out such behavior as being a successful attack."
Will a meaning of the whole sentence change if I omit this word "being"?
I don't know why the word "being" needs to exist in this clause.
