Multidomain Network Based on Programmable Networks: Security Architecture

This paper proposes a generic security architecture designed for a multidomain and multiservice network based on programmable networks. The multiservice network allows users of an IP network to run programmable services using programmable nodes located in the architecture of the network. The programmable nodes execute codes to process active packets, which can carry user data and control information. The multiservice network model defined here considers the more pragmatic trends in programmable networks. In this scenario, new security risks that do not appear in traditional IP networks become visible. These new risks are as a result of the execution of code in the programmable nodes and the processing of the active packets. The proposed security architecture is based on symmetric cryptography in the critical process, combined with an efficient manner of distributing the symmetric keys. Another important contribution has been to scale the security architecture to a multidomain scenario in a single and efficient way.Publicad

Chapter 7 Security and Privacy Challenges of a Digital Government

Abstract: A digital government can be viewed as an amalgam of heterogeneous information systems that exchange high-volume information among government agencies and public and private sectors engaged in government business. This gives rise to several daunting multidomain security challenges as well as concern for citizen privacy. The success of a digital government infrastructure depends on how well it meets these challenges and its preparedness against numerous potential threats ranging from simple act of hacking to cyber-terrorism. In this paper, we outline these crucial security and privacy issues and present various solutions that are available and need to be further investigated. Key words: security, access control, privacy, multidomain environment 1
