Abstract

The embodiment of the invention provides a compressed sensing data secure transmission method based on DRPE, and relates to the technical field of data processing, and the method comprises the steps: obtaining a first plaintext image and a second plaintext image, and obtaining a first scrambled image and a second scrambled image through chaotic scrambling by employing a preset chaotic initial value c; performing P tensor compressed sensing on the first scrambled image and the second scrambled image according to a preset input initial value r to obtain a first compressed and encrypted image and a second compressed and encrypted image which are combined into a complex matrix; according to a preset first phase initial value d1 and a preset second phase initial value d2, decomposing the complex matrix to obtain a target decomposition matrix and an auxiliary decryption matrix; according to a preset XOR auxiliary matrix e, processing the target decomposition matrix to obtain a ciphertext image; encrypting c, r, d1, d2 and e to obtain encryption parameters; and transmitting the ciphertext image, the auxiliary decryption matrix and the encryption parameters. When the scheme provided by the embodiment of the invention is used for transmitting data, the data can be efficiently and safely transmitted.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a DRPE-based method for secure transmission of compressed sensing data. Background technique [0002] With the rapid development of the Internet of Things technology, the Internet of Things has developed from the communication between things to things to connect everything. At the same time, the processing of massive data has also become a key problem that needs to be solved urgently. For example, data transmission Communication delay and information security of data transmission, etc. [0003] In the prior art, compressed sensing (Compressed sensing, CS) is often used to firstly process the data to be transmitted, and then transmit the processed data. However, with the increasing amount of data, the current data processing technology still cannot solve the above problems. Contents of the invention [0004] The purpose of the embodiments of the present invention is to...
