Wireless technologies which are the most important development areas in the twenty-first century and Wireless Body Sensor Networks which are developed for use in health care continues to be the focus on attention of researchers. Wireless Body Sensor Networks are used for monitoring health signals such as body temperature, heart pulse, EEG, and ECG of the(More)
Low-Rate Wireless Personal Area Networks (LRWPANs) 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(More)
Wireless body area networks (WBAN) consist of wireless smart sensor nodes placed on, in or around the human body for medical monitoring systems, entertainment and ubiquitous computing. The nodes in WBAN are usually battery-powered and they send sensed data from a human body, including heart rate, temperature and ECG, etc. to the medical centre to monitor(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)
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)
