With the trade-off that ~

http://en.wikipedia.org/wiki/Timestamp is another way of preventing a replay attack. http://en.wikipedia.org/wiki/Synchronization should be achieved using a secure protocol. For example Bob periodically broadcasts the time on his clock together with a MAC. When Alice wants to send Bob a message, she includes her best estimate of the time on his clock in her message, which is also authenticated. Bob only accepts messages for which the timestamp is within a reasonable tolerance. The advantage of this scheme is that Bob does not need to generate (pseudo-) random numbers, with the trade-off being that replay attacks, if they are performed quickly enough i.e. within that 'reasonable' limit, could succeed.

I think "if" clause is the concessive clause and that "that" clause modifies "trade-off."
If my guesses are right, I'd like to know why "being' was used in "with the trade-off being."

Thank you in advance for your help.

" The transformation of "is" to "being" happens because the object of "with" has to be a noun phrase rather than a clause.

Thank you, GPY, for your kind answer. Emotion: smile
Then I'd like to know whether "with" introduce the noun "the trade-off that~", not

I'm not sure I understand your question. In the sentence you quote, the word "being" is included, as you can see. However, "with the trade-off that ~" also works, and there is no significant difference in meaning.
