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.
