Analytical efficiency evaluation of a network mobility management protocol for Intelligent Transportation Systems

One of the major concerns in an Intelligent Transportation System (ITS) scenario, such as that which may be found on a long-distance train service, is the provision of efficient communication services, satisfying users' expectations, and fulfilling even highly demanding application requirements, such as safety-oriented services. In an ITS scenario, it is common to have a significant amount of onboard devices that comprise a cluster of nodes (a mobile network) that demand connectivity to the outside networks. This demand has to be satisfied without service disruption. Consequently, the mobility of the mobile network has to be managed. Due to the nature of mobile networks, efficient and lightweight protocols are desired in the ITS context to ensure adequate service performance. However, the security is also a key factor in this scenario. Since the management of the mobility is essential for providing communications, the protocol for managing this mobility has to be protected. Furthermore, there are safety-oriented services in this scenario, so user application data should also be protected. Nevertheless, providing security is expensive in terms of efficiency. Based on this considerations, we have developed a solution for managing the network mobility for ITS scenarios: the NeMHIP protocol. This approach provides a secure management of network mobility in an efficient manner. In this article, we present this protocol and the strategy developed to maintain its security and efficiency in satisfactory levels. We also present the developed analytical models to analyze quantitatively the efficiency of the protocol. More specifically, we have developed models for assessing it in terms of signaling cost, which demonstrates that NeMHIP generates up to 73.47% less signaling compared to other relevant approaches. Therefore, the results obtained demonstrate that NeMHIP is the most efficient and secure solution for providing communications in mobile network scenarios such as in an ITS context.

Análisis de rendimiento de técnicas criptográficas en el protocolo de movilidad HIP

[ES]Este proyecto tiene como objetivo analizar el rendimiento de diferentes técnicas criptográficas que el protocolo de movilidad HIP puede utilizar para proporcionar los servicios de seguridad que se determinen. Lo primero que se hará será seleccionar los diferentes algoritmos criptográficos que HIP podría utilizar para cubrir los servicios de seguridad considerados más relevantes, estos son autenticación, confidencialidad e integridad de datos. A continuación se identificarán los parámetros más significativos en relación al rendimiento y se definirá un escenario y un plan de pruebas para realizar las mediciones. Posteriormente se realizarán las mediciones con los algoritmos criptográficos previamente seleccionados, y por último se analizarán y valorarán los resultados obtenidos para así determinar la eficiencia de cada algoritmo criptográfico.
