Abstract: The number of attempts to break modern encryption methods increases day by day and therefore the need for the design of systems to ensure higher security has occurred. This study aims, an encryption algorithm that combines the strong of asymmetric encryption algorithm and the rich dynamic behaviors of chaotic systems is developed. In this study, firstly a new chaotic system design with high dynamic features is performed and then circuit realization and analyses are made. A chaos based RNG (random number generator) is designed with the help of the new developed chaotic system, NIST and FIPS tests are run. Chaos based hybrid RSA (CRSA) encryption algorithm design in which RNG and RSA algorithms are used together is performed. Text and image encryption is carried out with the algorithm and security analyses of these applications are made. Security analyses results are compared with classical RSA algorithm. It is observed that the developed CRSA algorithm provided better results than RSA algorithm in security tests.
