用简单物理模型构建通用对称加密系统

摘要

Digital objects, such as images, videos, digital warehouse are diverse in the sense of dimension and representation-precision. Conventional encryption algorithms treat all digital objects as one-dimensional data, thus they cannot make it effective to take advantage of their spatial characteristics. A cryptosystem is constructed by combining RE arrays with extended HPP model we proposed. The cryptosystem is applicable to digital object of arbitrary dimension and representation-precision. Moreover, it has the merits of spatiality, parallelism, and high efficiency. Experimental results demonstrate that the cryptosystem has satisfactory randomness and sensitivity.%提出了扩展HPP模型,并与RE阵列结合,构建了一个对称加密系统.该系统适用于任意维度和精度的数字对象,并具有空间性、并行性和高效性的特点.实验结果表明,加密系统具有良好的随机性和敏感性.
