Modelo de evaluación de requerimientos de privacidad, seguridad y calidad de servicio para aplicaciones médicas móviles / Model of assessment of requirements of privacy, security and quality of service for mobile medical applications

Resumen Introducción: El desarrollo de tecnologías móviles ha facilitado la creación de aplicaciones mHealth, las cuales son consideradas herramientas clave para la atención segura y de calidad a los pacientes de poblaciones apartadas y con carencia de infraestructura para la prestación de servicios de salud. El artículo considera una propuesta de un modelo de evaluación que permite determinar las debilidades y vulnerabilidades a nivel de seguridad y calidad de servicio (QoS) en aplicaciones mHealth. Objetivo: Realizar una aproximación de un modelo de análisis que apoye la toma de decisiones referentes al uso y producción de aplicaciones seguras, minimizando el impacto y la probabilidad de ocurrencia de los riesgos de seguridad informática. Materiales y métodos: El tipo de investigación aplicada es de tipo descriptivo, debido a que se detallan cada una las características que deben tener las aplicaciones móviles de salud para alcanzar un nivel de seguridad óptimo. La metodología utiliza las normas que regulan las aplicaciones y las mezcla con técnicas de análisis de seguridad, empleando la caracterización de riesgos planteadas por Open Web Application Security Project -OWASP y las exigencias de QoS de la Unión Internacional de Telecomunicaciones -UIT. Resultados: Se obtuvo un análisis efectivo en aplicaciones reales actuales, lo que muestra sus debilidades y los aspectos a corregir para cumplir con parámetros de seguridad adecuados. Conclusiones: El modelo permite evaluar los requerimientos de seguridad y calidad de servicio (QoS) de aplicaciones móviles para la salud que puede ser empleado para valorar aplicaciones actuales o generar los criterios antes de su despliegue.

Abstract Introduction: The development of mobile technologies has facilitated the creation of mHealth applications, which are considered key tools for safe and quality care for patients from remote populations and with lack of infrastructure for the provision of health services. The article considers a proposal for an evaluation model that allows to determine weaknesses and vulnerabilities at the security level and quality of service (QoS) in mHealth applications. Objective: To carry out an approximation of a model of analysis that supports the decision making, concerning the use and production of safe applications, minimizing the impact and the probability of occurrence of the risks of computer security. Materials and methods: The type of applied research is of a descriptive type, because each one details the characteristics that the mobile health applications must have to achieve an optimum level of safety. The methodology uses the rules that regulate applications and mixes them with techniques of security analysis, using the characterization of risks posed by Open Web Application Security Project-OWASP and the QoS requirements of the International Telecommunication Union-ITU. Results: An effective analysis was obtained in actual current applications, which shows their weaknesses and the aspects to be corrected to comply with appropriate security parameters. Conclusions: The model allows to evaluate the safety and quality of service (QoS) requirements of mobile health applications that can be used to evaluate current applications or to generate the criteria before deployment.

QoS awared power and admission controls based on non-cooperative game theory in wireless networks / 西安交通大学学报·英文版

In order to better accommodate heterogeneous quality of service (QoS) in wireless networks, an algorithm called QoS-aware power and admission controls (QAPAC) is proposed. The system is modeled as a non-cooperative game where the users adjust their transmit powers to maximize the utility, thus restraining the interferences. By using adaptive utility functions and tunable pricing parameters according to QoS levels, this algorithm can well meet different QoS requirements and improve system capacity compared with those that ignore the QoS differences.

The Transmission Performance Evaluation of Remote Healthcare Data over Secure Satellite Network / 대한의료정보학회지

OBJECTIVES: We have not only examined telemedicine scenario but also applied IPSec(AH, ESP) algorithms under VPN(Virtual Private Network) for performance evaluation of telemedicine system's security and transmission. METHODS: In this study, we applied IPSec(AH, ESP) algorithms under VPN(Virtual Private Network) protocol when transmit healthcare data through Satellite Network. At that time, we evaluated performance of telemedicine system through RTT(Round Trip Time), Jitter, Bandwidth that indicate to QoS(Quality Of Service). RESULTS: It is possible to transfer remote healthcare data over Satellite Network under provided image of 15 frame and bio-signal of 10 kbps and RTT(Round Trip Time) of 774.53ms, Jitter of 25.2ms. But applying IPsec(AH, ESP) under VPN(Virtual Private Network), it is frequently happened distortion of image data affected SHA-1 and 3DES algorithm. CONCLUSION: In this study, it is possible to use telemedicine system for Secure Satellite Network, but demand to be based QoS(Quality Of Service) limited. We expected that it is possible to use the designed system in the disaster area.

A PARALLEL SWITCH FABRIC BASED ON CROSSBAR / 药物分析学报

With the increase of link rate, the arbitrator of centralized switch fabric becomes too complicated to implement. A parallel switch fabric based on crossbar, named as PSFBC (Parallel Switch Fabric Based on Crossbar), has been proposed in this paper. PSFBC is composed of k switches whose rate is 1/k of link', these switches exchange cells in parallel; this increases the arbitrator's period and make it easy to implement. Load is evenly distributed to each switch with FCFS (First Come First Serve) rule, it can keep the order of cells in one stream. A multi-class queue scheduling policy is used in PSFBC to ensure the quality of realtime streams. Experiments show that the load on each switch in PSFBC is well balanced, its average delay of cells is little and its performance is very close to centralized switch; and with the increase of number of parallel switches, the loss of PSFBC's performance keeps very small, it becomes easier to implement.
