A Random Bit Generator Using Chaotic Maps
Chaotic systems have many interesting features such as sensitivity on initial condition and system parameter, ergodicity and mixing properties. In this paper, we exploit these interesting properties of chaotic systems to design a random bit generator, called CCCBG, in which two chaotic systems are cross-coupled with each other. To evaluate the randomness of the bit streams generated by the CCCB...
متن کاملZigzag map: A variability-aware discrete-time chaotic-map truly random number generator
In this letter, we present a circuit implementation for the discrete-time zigzag map, which exhibits high speed, low power consumption, and above all resilience to process variations. Circuit parameter variations result in alteration of the chaotic map parameters, such as the slope and the location of the breakpoints in the map, which in turn degrade the randomness of the generated bit sequence...
متن کاملA Pseudo-Random Bit Generator Using Three Chaotic Logistic Maps
A novel pseudo-random bit generator (PRBG) using three chaotic logistic maps is proposed. The algorithm generates at each iteration sequences of 32 bit-blocks by starting from randomly chosen initial seeds. The impact of relying on IEEE 754-2008 floating-point representation format for the generator is also taken into account. The performance of the generator is evaluated through various statis...
متن کاملImproving the Security of Pseudo-random Sequence Generator Based on Chen Chaotic System ?
In this letter, the cause of vulnerability of the original pseudo-random sequence generator based on Chen chaotic system is analyzed, and the corresponding enhancement methods are proposed. Transient data produced by the calculation among fixed-point numbers is used to improve the performance of the original scheme. Statistical tests and security analysis indicate that the modified scheme is mo...
متن کاملChaotic Map Based Random Image Steganography Using LSB Technique
Steganography play an important role to transfer secret data over insecure network. Moreover digital images are taken as a cover to communicate the sensitive data. One of the simplest approach of embedding the secret data into cover image is Least Significant Bit (LSB) method. This paper aims to propose a new symmetric key based image hiding technique. Pseudo random keys are generated by using ...
