In this study, a chaos based encryption method with nonlinear equations in MATLAB environment is proposed to increase communication security. Encryption methods that generated by using the properties of three different chaos generators are analyzed. Logistic Map, Pinchers Map and Sine-Circle Map chaos generators which are commonly referred in the literature(More)
WPANs) have widespread usage for industrial applications because of being small, power-efficient, and low-cost. Therefore security is important issue for LR-WPANs. The IEEE 802.15.4 standard is one of the most common solution for LR-WPANs that defines only the physical and data-link layers of the OSI model. For this reason most of security issues are(More)
In this paper, a MATLAB-based graphical user interface (GUI) software tool for general biomedical signal processing and analysis of functional neuroimaging data is introduced. Specifically, electroencephalography (EEG) and electrocardiography (ECG) signals can be processed and analyzed by the developed tool, which incorporates commonly used temporal and(More)
In this paper, we present a new voice encryption for voice communication system. It is based on permutation and substitution of voice samples using transform domains and secret keys in time. To increase the security we design the system such that it is multilevel in the sense that two chaotic maps are used. This provides the encrypted signal with a high(More)
An interface has been designed for Volterra series method which is used for non-linear systems analysis. Simplified computation algorithm, developed for Volterra frequency response functions, has been used in the designed interface. Frequency response function has been obtained for a sample model. Gain and phase graphics have been ploted for the obtained(More)
Original scientific paper Processes on Wireless Sensor Networks (WSN) and their areas of use have become more widespread, and the issue of net-work security has appeared as one of the primary necessities. As power of the processor, memory and energy sources are limited on wireless sensor network nodes, traditional encryption structures are not found(More)
Nowadays, despite there are many advanced technological applications to maintain the security of buildings, premises or regions, human intervention is necessary when considering both economical facts and the effectiveness of the systems especially for the security of military zones. In the presented work, a highly secure system has been designed. With the(More)
There exists a great number of work related to chaotic systems investigated by many researchers, especially about Lorenz chaotic system. If the order of differentiation of variables are fractional, the systems are called fractional chaotic systems. In this work a webbased interface is designed for fractional composition of five different chaotic systems.(More)
