With the aim of tackling insufficient security in chaotic encryption algorithm for digital images Optical Access Network, a color image scheme combining non-degenerate discrete hyperchaotic system and deoxyribonucleic acid (DNA) dynamic encoding is proposed. First, new constructed with all positive Lyapunov more complex characteristics. Furthermore, key sequence based on generated using plaintext correlation to achieve effect secret key. Next, binary bit-planes permutation performed one...
With the arrival of age big data, amount and types data in process information transmission have increased significantly, full-disk encryption mode used by traditional algorithms has certain limitations times. In order to further improve bandwidth efficiency digital images effectiveness image transmission, this paper proposes an algorithm high-quality restoration using DCT frequency-domain compression coding chaos. Firstly, hash value is for generation key with plaintext correlation, then...
In order to further improve the information effectiveness of digital image transmission, an image-encryption algorithm based on 2D-Logistic-adjusted-Sine map (2D-LASM) and Discrete Wavelet Transform (DWT) is proposed. First, a dynamic key with plaintext correlation generated using Message-Digest Algorithm 5 (MD5), 2D-LASM chaos obtain chaotic pseudo-random sequence. Secondly, we perform DWT from time domain frequency decompose low-frequency (LF) coefficient high-frequency (HF) coefficient....
The era characterized by an exponential increase in data has led to the widespread adoption of intelligence as a crucial task. Within field mining, frequent episode mining emerged effective tool for extracting valuable and essential information from event sequences. Various algorithms have been developed discover episodes subsequently derive rules using frequency function anti-monotonicity principles. However, currently, there is lack specifically designed that encompass user-specified query...
Microsoft Office is the most popular office software. document security mainly carried out through encryption by software function. But as new decoding method put forward and computer speed accelerated rapidly, has been questioned. This paper analyzed whole process of 2013 file encryption/decryption, designed a contrast experiment with former version 2010, then cracked respectively password on CPU computing GPU platform brute-force method, experimental data were obtained time indicator. It...
