High performance Internet traffic inspection and layer-7 content analysis have become essential functions of high speed networks. Over the past decade several DPI systems have evolved targeting specific issues related to traffic management, user/application policing, intrusion detection/prevention, URL/malicious/unwanted content filtering. Snort, OpenDPI, Bro, L7-filter, ClamAV are a number of open-source...
This paper presents the implementation of a configuration server for a SNTP synchronization platform which implements accurate synchronization solutions for Remote Terminal Units commonly used in industrial control processes. The configuration server provides settings to others platform devices using the BOOTP protocol and an interface that allow to administer the system. This environment requires...
Agent-systems can bring important benefits especially in applications scenarios where highly distributed, autonomous, intelligence, self-organizing and robust systems are required. Furthermore, high levels of autonomy and self-organization of agent systems provide excellent support for development of systems with high dependability requirements. Two main research areas that fall in this category are...
Mobile agents are processes that can migrate autonomously from new hosts. Despite of the huge number of fields of application of this technology, a lack in the security exists. The main approach of this work is based on the provision of a secure execution environment for mobile agents. Our approach is based on the idea of the trusted migration. This trusted migration is reached by means of the use...
Software agents are a promising computing paradigm. Scientific community has devoted important efforts to this field [1]. Indeed, several important applications exist based on this technology. Despite of their benefits, the lack of the appropriate security mechanisms for agent based systems represents a barrier for the widespread use of this technology. Additionally, the application of the current...
Agent-based computing represents a promising paradigm for distributed computing. Unfortunately the lack of security is hindering the application of this paradigm in real world applications. The protection of malicious hosts is considered the most difficult security problem to solve in mobile agent systems. In this paper we provide a mechanism that aims to solve the problem of the malicious hosts....
Ambient intelligence (AmI) refers to an environment that is sensitive, responsive, interconnected, contextualized, transparent, intelligent, and acting on behalf of humans. AmI environments impose some constraints in the connectivity framework, power computing as well as energy budget. This makes of AmI a significantly different case within distributed systems. The combination of heterogeneity, dynamism,...
This contribution presents the design and implementation of a SNTP client module suitable for IEC 61850 environments fully done in hardware. The module is able to provide synchronization and accurate time reference within a microsecond with respect to a SNTP server, in a extremely compact, cost-effective and low power device completely implemented in a low grade FPGA chip. Therefore it can be an ideal...
