An Image Encryption Scheme Based on Lorenz Hyperchaotic System and RSA Algorithm

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021
This research proposes a new image encryption scheme based on Lorenz hyperchaotic system and Rivest–Shamir–Adleman (RSA) algorithm. Firstly, the initial values of the Lorenz hyperchaotic system are generated by RSA algorithm, and the key stream is produced iteratively.

Multimedia Communication Security in 5G/6G Coverless Steganography Based on Image Text Semantic Association

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021
Recently, researchers have shown that coverless steganography is relatively safe. On this basis, to improve the payload of the coverless steganography, a novel semiconstruction coverless steganography algorithm is introduced in the paper. Firstly, web crawler technology is applied to crawl a wide range of small icons and hot news images from the ...
