Abstract

In this study, a user interface has been designed for chaos based image encryption applications
in LabVIEW. First, a random number generator was designed via a chaotic system that analyzed in LabVIEW.
Through to the interface developed in this design, the initial values, system variables and how many bits of
random numbers will be generated are entered by the user. Moreover, the phase portraits and time series of
the system can be observed by the user through this interface. The random numbers produced were tested
on NIST-800-22 to measure the reliability of the system. In addition, an interface design that enables easy
encryption can be done by selecting random numbers and images produced with the algorithm developed in
LabVIEW. The reliability of the application was verified by passing commonly accepted tests in the literature
such as histogram entropy, correlation, UACI, NPCR. While the result values of NPCR test for y, z phases
are 0,99573 and 0,99605, the UACI result values are 0,29265 and 0,2939. Results shows that the proposed
software is reliable.
