摘要：This article presents an information permutation and breaking scheme to construct a low-cost encryption scheme. The proposed encryption scheme preserves the security requirements of a general encryption scheme. The presented research uses information entropy to depict the one-way property and tries to use entropy to study the one-way property. The authors also present an estimation of the reasonable size of the seed set of a pseudo-random number generator
