Chaos Based Pseudo Random Bit Generator Design and Its Application in Secure Image Encryption

Security and privacy problems in communication systems social media platforms where digital image/video are shared almost always, have attracted researchers interest on information security. Starting from this point of view, a novel one-dimensional chaotic maps based pseudo random bit generator is proposed to make significant contribution the literature about protection personal data any network. Electronic circuit realizations Logistic Tent as entropy source designed Orcad-Pspice environment state variables inputted post-processor algorithm. The rest main blocks design built up fixed-point binary conversion algorithm, XOR processor H function post-processor. generated series tested by using NIST 800.22 statistical test suite applied color image encryption order show effectiveness design. Cryptanalysis processes such histogram, NPCR-UACI correlation analysis demonstrated. Analysis results that can be used successfully many secure transmission applications.
