GIFT: A Small Present Towards Reaching the Limit of Lightweight Encryption

摘要: In this article, we revisit the design strategy of PRESENT, leveraging all advances provided by research community in construction and cryptanalysis since its publication, to push up limits. We obtain an improved version, named GIFT, that provides a much increased efficiency domains (smaller faster), while correcting well-known weakness PRESENT with regards linear hulls. GIFT is very simple clean outperforms even SIMON or SKINNY for round-based implementations, making it one most energy efficient ciphers as today. It reaches point where almost entire implementation area taken storage Sboxes, any cheaper choice Sbox would lead weak proposal. essence, composed only bit-wiring, but natural bitslice data flow ensures excellent performances scenarios, from area-optimised hardware implementations fast software on high-end platforms. conducted thorough analysis our state-of-the-art cryptanalysis, provide trong bounds differential/linear attacks.
