格气对称密码

Lattice Gas Symmetric Cryptography

Laurent Signac

摘要:

格点气元胞自动机(Lgca)是一种模拟粒子在格点上运动的特殊元胞自动机。我们使用一组特殊的Lgca规则,称为hpp,在数据块中混合位,并获得对称加密算法。加密和解密密钥是网格(壁)上的扰动位点的位置。基本上,本文提出了一种新的方法来执行密码运算,基于元胞自动机。在本文中,我们展示了我们的算法的几个特点:典型的块大小(2^(2n-1)),密钥长度(2 ^n),轮数(2^(n+1))。我们还评估雪崩和严格雪崩属性方面的关键和纯文本。最后,我们强调了我们的方法的不足之处,并给出了解决这些问题的线索。

英文摘要:

Lattice gas cellular automata (Lgca) are particular cellular automata that imitate the behavior of par- ticles moving on a lattice. We used a particular set of Lgca rules, called hpp, to mix bits in data blocks and obtain a symmetric cryptographic algorithm. The encryption and decryption keys are the positions of perturbation sites on the lattice (walls). Basically, this paper presents an original way to perform cryp- tographic operations, based on cellular automata. In this paper, we show several characteristics about our algorithm: typical block size (2^(2n-1) ), key-length (2^n ), number of rounds (2^(n+1) ). We also evaluate avalanche and strict avalanche properties with respect to key and plain text. Finally, we highlight the underbellies of our method and give clues to solve them.
