Selected papers from Trusted Internet Workshop (TIW) 2004

Security was not an inherent feature of the Internet when it was originally deployed. The tremendous success and growth of the wired Internet has led to a wealth of applications ranging from e-commerce to grid computing. Quality of Service (QoS), reliability, and security are necessities for many of the applications. Furthermore, the growing number of wireless devices capable of connecting to Internet has made QoS, reliability, and security important issues in the wireless world as well. A considerable amount of research has been done on all aspects highlighted above, and much more remains to be done to secure the next-generation Internet and provide QoS. The term Trusted Internet refers to the next generation Internet that is capable of providing QoS, reliability, and security guarantees to the applications and end-users. We are pleased to present before you this special issue of the Journal of High Speed Networks (JHSN) consisting of selected papers from the Third Annual Trusted Internet Workshop (TIW) 2004 that was held in conjunction with the International Conference on High-Performance Computing (HiPC) on December 22, 2004 in Bangalore, INDIA. The goal of the workshop was to provide a forum for researchers and practitioners to present and discuss their work and exchange ideas in the areas of Internet QoS, Internet Reliability, and Internet Security. A similar special issue consisting of selected papers from the 2003 workshop was published last year as JHSN special issue, Vol. 13, no. 4, Dec. 2004. The workshop received 30 paper submissions. Each submission was reviewed by at least three reviewers, following which nine papers, some of which were regular and the remaining short, were selected for presentation at the workshop. For this special issue, we have selected six of these papers. Each of these six papers is an enhanced version of their workshop counterparts, and have been reviewed again by the special issue co-editors. The papers represent a good sample of the ongoing research in this area, and we hope that these will stimulate further advances in this area. The paper titled “SCIT-DNS: Critical infrastructure protection through secure DNS server dynamic updates” by Y. Huang, D. Arsenault and A. Sood presents a secure implementation framework for DNS servers. The framework called “Self-Cleaning Intrusion Tolerance” eliminates the risk of keeping the private keys of the DNS server online to sign dynamic updates, and uses hardware redundancy. An implementation of the framework is also presented. The paper titled “SPEE: A Secure Program Execution Environment tool using code integrity checking” by O. Gelbart, B. Narahari and R. Simha attempts to create a secure program execution environment by complementing the existing code security tools with the addition of program checking and program/user authentication. To this
