comment Proving the semantic security of the One Time pad
Okay, so, to sum up your answer: there is no explicit proof for the semantic security, because we have already proven the shannon security, which is a stronger requirement and implies semantic security.

comment Why is triple-DES using three different keys vulnerable to a meet-in-the-middle-attack?
@owlstead Thanks for the Link. I would never use 3DES anyway, this was just a question raised and not answered by the Wikipedia article.

comment Why is triple-DES using three different keys vulnerable to a meet-in-the-middle-attack?
Thanks for your answer, but the question I was trying to ask is why Meet in the Middle won't work (or will not make the attack "cheaper") on 2 keys as opposed to three keys. Or is 114 operations a fixed value for meet-in-the-middle? EDIT: Seeing your edit, it now is a bit clearer to me what you mean. Thanks.
