Rhouma, R., Solak, E., Arroyo, D., Li, S., Alvarez, G. & Belghith, S. (2009). Comment on “Modified baptista type chaotic cryptosystem via matrix secret key” [phys. lett. A 372 (2008) 5427]. Physics Letters A, 373(37), 3398-3400. doi:10.1016/j.physleta.2009.07.035Özet
In this comment, we analyze a recently proposed Baptista-like cryptosystem and show that it is not invertible. Others weaknesses are also reported. A modified version of this cryptosystem is proposed to show how to overcome the non-invertibility.
