In this paper, we quantify the performance analysis of PingPong-128 keystream generator for wireless sensor networks. Although, PingPong-128 is not a standard stream cipher but still PingPong-128 keystream generator is an idea for resource constrained WSNs and can be widely used in the applications of secure communication, where the communication nodes have limited computation processing and storage...
Recent advancement in ubiquitous healthcare evolves to new challenges in ubiquitous communications. Secure communication in wireless sensor networks (WSNs) is one of the important issues, especially, when WSN comes to ubiquitous healthcare, where security is main requirement in sensor devices, communication and continuous real-time monitoring of patient in hospital or home network. WSN requires efficient...
Problem statement: Most of Medicare data exchanges are textual, poorly structured and often not accessible by clinical professionals. Otherwise, the variety of medical applications and medical standards makes difficult sharing and communicating Medicare data in a highly heterogeneous environment. Approach: XML and related standards (XML schema, XSL) provided an infrastructure that might change the...
In wireless sensor networks (WSNs); routing protocols are one of the main issues in existing research. These protocols make the best use of limited resources, particularly the energy efficiency and effectiveness of data dissemination. Few of them discuss security issues in homogenous sensor networks which consume much power, have poor performance limits and less scalability. In order to attain the...
A continuously running-code optical CDMA system useful for secure communications is reported. The system utilises acousto-optic modulator-based pulse shapers as spectral phase en-/decoding devices, which are capable of microsecond-scale code sequence refresh rates. The codes are generated on-the-fly by a stream cipher. Transmit/ receive code synchronisation is independent of the data stream, allowing...
Security is one of the major issue for the ubiquitous sensor networks' (USNs) applications. The evolution of ubiquitous sensor networks provides a unique solution for many ubiquitous information services. Apparently, it challenges the data security and secrecy due to its hostile deployment which is not robust to physical attacks from restricted sources. In order to resolve, the security issue that...
The possibility of using purely text stream (keyboard-enterable) as carrier of malware is under-researched and often under estimated. A text attack can happen at multiple levels, from code-injection attacks at the top level to host-compromising text-based machine code at the lowest level. Since a large number of protocols are text-based, at times the servers based on those protocols use ASCII filters...
Optimizing the single FPGA board resource as a simulator in a multi user environment regardless of the physical distance improved by TCP/IP. It is important step for IP and system development to use FPGA and IP core to design and improve flow of multi user data in a high speed communication internet environment and optimal utilization of available bandwidth. A user can connect either by Wi-Fi, Wi-Max...
