Colour image encryption via fractional chaotic state estimation. Issue 10 (1st October 2018) - Montesinos‐García, Juan J.
Abstract : This study introduces an encryption algorithm for colour RGB images and text, the encryption is based on the synchronisation of fractional chaotic systems, the synchronisation has the topology of master–slave, where the transmitter is the master system and the receiver is the slave system, this last one is designed as a new smoothed sliding modes state observer for fractional chaotic systems. The encryption algorithm provides security against common cryptographic techniques, including known and chosen plaintext attacks.
