Synchronization precision analysis of a fractional-order hyperchaos with application to image encryption

Synchronization precision analysis of a fractional-order hyperchaos with application to image encryption

This paper proposes an effective image encryption algorithm based on the transformational prospective synchronization of a fractional-order hyperchaotic system. Compared with other chaos-based algorithms, fractional orders and synchronization precision are added as secret keys. It is shown that frac...
