Further Observations on Smart-Card-Based Password-Authenticated Key Agreement in Distributed Systems

This paper initiates the study of two specific security threats on smart-card-based password authentication in distributed systems. Smart-card-based password authentication is one of the most commonly used security mechanisms to determine the identity of a remote client, who must hold a valid smart card and the corresponding password to carry out a successful authentication with the server. The authentication is usually integrated with a key establishment protocol and yields smart-card-based password-authenticated key agreement. Using two recently proposed protocols as case studies, we demonstrate two new types of adversaries with smart card: 1) adversaries with pre-computed data stored in the smart card, and 2) adversaries with different data (with respect to different time slots) stored in the smart card. These threats, though realistic in distributed systems, have never been studied in the literature. In addition to point out the vulnerabilities, we propose the countermeasures to thwart the security threats and secure the protocols.

Encapsulation of Micro Engineering Tools in a Co- Operative Jyaguchi Computing Infrastructure

Micro engineering tools and services face many issues and limitations in terms of modularity, and usability with regards to their availability and scalability. Scalability may suffer due to the limitation of service granularity as service objects sometimes may require to deliver in low bandwidth network infrastructures. Jyaguchi platform supports highly dynamic and interactive service development process by which developers can design services as per their requirement functionalities which can be micro, macro or mega services. In this paper we discuss particularly about the development process of micro services. The qualities of a micro-service are not limited to its performance metric, but are designed to maintain simplicity and may even consist of fully-functional and loosely coupled applications. These services can be utilized enabling a higher level of usability. Usability is maintained by reducing the granularity and complexity of functionalities of a service. However, Jyaguchi services have potential to increase its granularity without breaking its underlying architecture. The service oriented architecture of Jyaguchi platforms also allow for these services to dynamically deliver to the remote clients and still keep the persistent state until the client terminate the service. We also realize that micro engineering services that are distributed locally or globally should be categorized during the design phase. These services should be allowed to change its granularity in demand-respond manner based on micro, macro and mega service model instead of keeping those services static. A working model of Jyaguchi platform that can deliver these kinds of services is also discussed in this paper which incorporates all these aspects.

Dynamic Scheduling and Real-Time Rendering for Large-Scale 3D Scenes

3D visualization and real-time rendering of large-scale scenes is an important task of virtual reality. In this paper, different from local loading and roaming of the scenes, we focus on dynamic loading and real-time roaming, based on the remote servers and clients, to facilitate the efficient transmission and reduce the transmission time. More specifically, a novel dynamic scheduling algorithm in the client side is used to optimize the loading and real-time rendering performance, i.e., this method can dynamically load and unload the partitioned data blocks from the server side according to the roaming viewpoints so that we can realize the infinite roaming of a large scale scene. In order to accommodate different networking scenarios, we also design a multi-resolution scheme for those server-stored scene blocks according to different communication channel conditions, so that the most suitable resolution scheme can be automatically chosen. As shown in the experiments, our method only requires a small amount of memory overhead, while efficiently realizes infinite roaming of the large city scenes.

Acceptability of Telemedicine and Other Cancer Genetic Counseling Models of Service Delivery in Geographically Remote Settings

This work examined acceptability of cancer genetic counseling models of service delivery among Maine residents at risk for hereditary cancer susceptibility disorders. Pre-counseling, participants ranked characteristics reflecting models of care from most to least important including: mode-of-communication (in-person versus telegenetics), provider level of training (genetic specialty versus some training/experience), delivery format (one-on-one versus group counseling), and location (local versus tertiary service requiring travel). Associations between models of care characteristic rankings and patient characteristics, including rural residence, perceived cancer risk, and perceived risk for a hereditary cancer risk susceptibility disorder were examined. A total of 149/300 (49.7% response rate) individuals from 11/16 Maine counties responded; 30.8% were from rural counties; 92.2% indicated that an important/the most important model of care characteristic is provider professional qualifications. Among other characteristics, 65.1% ranked one-on-one counseling as important/the most important. In-person and local counseling were ranked the two least important characteristics (51.8% and 52.1% important/the most important, respectively). Responses did not vary by patient characteristics with the exception of greater acceptance of group counseling among those at perceived high personal cancer risk. Cancer telegenetic services hold promise for access to expert providers in a one-on-one format for rurally remote clients.

Automatic configuration of routing control platforms in OpenFlow networks

RouteFlow provides a way to run routing control platforms (e.g. Quagga) in OpenFlow networks. One of the issues of RouteFlow is that an administrator needs to devote a lot of time (typically 7 hours for 28 switches) in manual configurations. We propose and demonstrate a framework that can automatically configure RouteFlow. For this demonstration, we use an emulated pan-European topology of 28 switches. In the demonstration, we stream a video clip from a server to a remote client, and show that the video clip reaches at the remote client within 4 minutes (including the configuration time). In addition, we show automatic configuration of RouteFlow using a GUI (Graphical User Interface).

DESIGN OF FUZZY LOGIC CONTROLLER FOR ONLINE SPEED REGULATION OF DC MOTOR USING PWM TECHNIQUE BASED ON LABORATORY VIRTUAL INSTRUMENT ENGINEERING WORKBENCH

This study details online speed regulation of DC motor using PWM technique based on LabVIEW. A fuzzy logic controller is designed to change the pulse width of switching signal applied to the converter and thereby the voltage fed to the armature of the separately excited DC motor to regulate the speed. The proposed system is connected to the server computer using a Data Acquisition Card (DAQ) and the server computer is configured to access remote client computer using Web publishing tool in LabVIEW. Now the speed of the DC motor can be controlled by a remote client computer with Internet connection. Laboratory Virtual Instrument Engineering Workbench (LabVIEW) is a graphical programming environment for creating custom applications that interact with real-world data or signals in fields such as science and engineering. The proposed online control system has been implemented to control the speeds of two different motors and the experimental results are plotted. The conventional controllers need design objectives such as steady state and transient characteristics of the closed loop system to be specified. But the designed fuzzy logic controller overcomes the problems with uncertainties in the plant parameters. The proposed online control technique saves time and reduces the manpower.

Analysis and evaluation of the establishment and maintenance of paths in a MANET used for industrial process monitoring

The use of wireless networks is having an ever greater impact on systems controlling automation, industrial manufacturing, distributed control and supervision. Wireless technologies in particular have penetrated quickly the area of control of public utilities networks, and typical examples of this are remote control and supervision of large water, gas or electricity distribution networks. These types of networks are usually formed of a central station and different remote stations, and remote clients who are able to remotely monitor or even control the working of the system. To improve the use of the system, the remote stations must have the capacity to exchange information between each other and with the central station. The spontaneous generation of wireless networks in remote stations to exchange information between workers is a possible solution. Taking into account the characteristics of this type of monitoring system, the paper has proposed a scenario (number of nodes, area size, mobility) and has modeled, using stochastic activity networks (SAN), the operation of an ad hoc network that uses a reactive routing protocol to determine if the network is able to offer the typical services of these facilities (images or video streaming and alerts).

Does a DVD improve compliance with home exercise programs for people who have sustained a traumatic hand injury? Results of a feasibility study

Purpose: This feasibility study sought to determine if compliance and understanding of a home exercise program following a traumatic hand injury is improved when patients are provided with a DVD and a brochure when compared to using brochures only. Method: Patients who presented with a traumatic hand injury and commenced on a hand therapy protocol were randomly assigned into two groups. The control group received brochures while the experimental group were provided with exercise instructions on DVD as well as brochures. Compliance was measured through the use of exercise diaries, clinic attendance, a checklist to measure correctness and understanding of exercises and a follow-up survey. Results: No significant improvement was found in the mean exercise compliance score (p = 0.344) between the intervention and control groups. From the survey results almost half of all participants reported that pain interfered in their ability to perform their home exercises and a third acknowledged that time limited their ability to perform their exercises. Conclusion: Findings demonstrate the multidimensional nature of compliance. The provision of DVD technology, while not shown to cause a statistically significant change in overall compliance, did help improve understanding of exercises; as such DVDs could be utilised as part of a program that facilitates the patient--therapist relationship.Implications for RehabilitationLimited time and level of pain are highlighted as reasons for non compliance with exercise and treatment programs.The use of DVDs can improve understanding and execution of exercises and can be part of a treatment program that facilitates increased patient therapist contact for rural and remote clients.

A Real-time BLE Enabled ECG System for Remote Monitoring

A major requirement of ubiquitous healthcare systems consists in the provision of low power usage, battery operated devices that are used in long term patient monitoring. Thus far, researchers have tried to adapt various short range technologies such as IEEE802.15.4, classical Bluetooth etc., to achieve this goal. The IEEE802.15.4 was, by excellence, widely deployed because of its low power and its security features compared to technologies such as the classical Bluetooth. However, the Bluetooth Special Interest group has recently announced Bluetooth 4.0 with low energy technology (BLE) for low power personal area networked devices, which offers more compelling features in various aspects when compared to IEEE802.15.4. This makes its evaluation for healthcare applications an urgently needed endeavour. In this paper, we present a BLE-based remote health monitoring system in which we have interfaced an ECG simulator directly to a BLE enabled CC2540 wireless sensor node (a system-on-chip (SoC) for Bluetooth low energy applications, from Texas Instruments). The node acts as a slave to the Master BLE device. In our system, we have used a BLE112 module (from Bluegiga) as a slave node while for the master we have used a BLE USB dongle connected to a PC in order to manage data received from the sensor node. A server application running on the PC uses a TCP-based connection over the network interface in order to enable remote monitoring. Any remote client can connect to the server and receives live updates from the sensor node. We have developed a LabVIEW based TCP client application to provide this functionality. An ECG simulator was used to generate ECG signals for different heartbeat rates that were sent through the BLE enabled network. The waveforms received at remote station using the developed system were found to conform exactly to those captured using a high resolution oscilloscope.
