Can anyone tell me where hyperchaotic system is used in real world, its applications? It'd be great if you could provide a literature to back any application as well. Thanks.

It is well known that if two or more Lyapunov exponents of a dynamical system are positive throughout a range of parameter space, then the resulting attractors are hyperchaotic. The importance of these attractors is that they are less regular and are seemingly "almost full" in space, which explains their importance in fluid mixing [Scheizer & Hasler, 1996, Abel et al., 1997, Ottino,1989; Ottino et al., 1992].
