An Image Encryption Scheme Synchronizing Optimized Chaotic Systems Implemented on Raspberry Pis

Guaranteeing security in information exchange is a challenge public networks, such as the highly popular application layer Message Queue Telemetry Transport (MQTT) protocol. On one hand, chaos generators have shown their usefulness masking data that can be recovered while having appropriate binary string. Privacy then accomplished by implementing synchronization techniques to connect transmitter and receiver, among millions of users, encrypt decrypt correct key. other chaotic sequences generated on Rapsberry Pis connected over MQTT. To provide privacy security, receiver (among devices) synchronized same key data. In this manner, paper shows implementation optimized Raspberry are wirelessly via MQTT for IoT The publisher encrypts interconnected devices, but decrypted subscribers sequence. image encryption system tested performing NIST, TestU01, NPCR, UACI statistical analyses.
