摘要
DES (data encryption standard)是一种密码学标准。但由于密钥空间小，限制了它的应用。在无理数的基础上，提出了一种增强子密钥随机性的改进方案，该方案采用无理数控制子密钥的排列，将其视为假混沌。此外，由数据控制的排列可以在通用CPU上高速执行。结果表明，该方案可以在不增加运行时间的情况下扩展密钥空间。
Improved DES algorithm based on irrational numbers
DES (data encryption standard) is a cryptographic standard. However, the applications of it are limited because of the small key space. Based on irrational numbers, an improved scheme that enhances the randomness of sub-key is proposed, in which the permutation is controlled by irrational number which is considered as false chaos. Moreover, the permutation controlled by data can be performed at high speed in generic CPU. It is shown that this scheme can expand the key space without costing any more time to run.
