Hi again. I've been puzzled by a number of answers and their explanations to some of the questions on Yusuf's Flash Cards, that frankly speaking leave me confused as to what the correct answer to provide would be.
For instance, when asked "What function does AH provide" I answered: Data integrity, Data origin authentication, and optionally Anti-replay protection. The answer given in the Flash Cards is Data integrity and Data origin authentication. The explanation that follows though states that AH provides data integrity checking, data origin authentication, and an optional replay protection. Would I be marked wrong for including "replay protection" when its clearly stated in the explanation but not in the answer, or would I be marked wrong for not including it in one of the provided services.
