WebWe revisit designing AND-RX block ciphers, that is, the designs assembled with the most fundamental binary operations—AND, Rotation and XOR operations and do not rely on existing units. Likely, the most popular representative is the NSA cipher SIMON, which remains one of the most efficient designs, but suffers from difficulty in security evaluation.

Web13 de jul. de 2014 · To avoid nit-picking, let’s keep it simple and assume that an individual block cipher does not use an algorithm that loses some of the effective security a key provides. Also, let’s assume that no known attacks exist. Would it be more correct to claim that the effective security of that cipher is equal the key size, or is it half the key size?
