The Community for Technology Leaders



Pages: pp. 1-3

During the past few years, IEEE TDSC established itself as one of the most competitive journals among the IEEE Transactions and in the field of computing, in general. As a consequence, we continue to attract nearly 200 submissions per year and have maintained an acceptance rate of about 10-12% for regular papers. At the same time, the publication quality has steadily increased thanks to higher quality submissions and their careful processing by a dedicated group of outstanding Editorial Board experts and reviewers. The increase in TDSC’s page budget during 2009 alleviated some concerns regarding the timeliness with which we are able to disseminate important research results. However, it is quite clear that a substantial number of interesting papers cannot be published unless the current page budget is increased. For example, an early editorial initiative of publishing the best papers of IEEE-sponsored dependability and security conferences could only be partially implemented due to page budget limitations. For this reason, we requested a 50 percent increase in the number of issues TDSC publishes per year, from four to six. This would not only raise the visibility of our journal within the scientific community but also attract new and exciting submissions. We anticipate that this increase will take effect at the earliest possible time, namely during 2011. We also look forward to transitioning to an online-only publication in 2011.

We are extremely privileged that the following six individuals have agreed to serve as members of the Editorial Board: Professors Yair Amir (Johns Hopkins University), Christopher Kruegel (University of California, Santa Barbara), Wenke Lee (Georgia Tech), David Taylor (University of Waterloo), Dr. David Powell (LAAS-CNRS, Toulouse), and Professor Frank Stajano (Cambridge University). They are all very prominent researchers in their respective areas of interest and their presence on the Board will undoubtedly attract added interest in TDSC. Their brief biographies are included below.

During the past four years, TDSC benefited from the outstanding expertise and unmatched dedication of our Associate Editors. The terms of service for two of these individuals, namely Professor Lorenzo Alvisi (University of Texas, Austin) and Professor Giovanni Vigna (University of California, Santa Barbara) ended in 2009, and on behalf of the Editorial Board, I would like thank them for their commitment, hard work, and good judgment during the past four years. As my own term of service as Editor-in-Chief ended on 1 January 2010, I would like to take this opportunity to express my gratitude to all of the authors who entrusted us with their research work, to all of the reviewers for their helpful and timely reports, and the entire Editorial Board and IEEE Computer Society Publications Staff for their unfailing assistance.

My heartfelt welcome and best wishes are extended to Professor Ravi Sandhu, the incoming Editor-in-Chief of TDSC. Ravi’s long and distinguished record as the founding Editor-in-Chief of ACM Transactions on Information and System Security and his deep commitment to IEEE professional activities give all of us the confidence that under his leadership this journal will continue to thrive.

Frank Stajano received the PhD degree in computer security at the University of Cambridge in 2000. In the same year, he accepted a lectureship at Cambridge and was elected a Toshiba Fellow, which took him to the company’s R&D headquarters in Japan for a year. As a tenured faculty member in the computer security group and the digital technology group at the University of Cambridge, his research interests revolve around three interconnected themes: systems security, privacy in the electronic society, and ubiquitous computing. He is the author of Security for Ubiquitous Computing (Wiley, 2002). A popular public speaker, he has given about 40 invited talks across America, Europe, and Asia. His academic career was preceded by several years as a research scientist in the computing, electronics, and telecommunications industries (Toshiba, AT&T, Oracle, and Olivetti) and therefore his research retains a strong practical orientation. He continues to consult for industry on various topics from systems security to strategic planning and innovation.
