This book constitutes the thoroughly refereed post-conference proceedings of the 9th International ICST Conference on Security and Privacy in Communication Networks, held in Sydney, Australia, in September 2013. The 26 revised full papers presented were carefully reviewed and selected from 70 submissions. The papers are grouped in topical sections on: security and privacy in mobile, sensor and ad hoc networks; malware, botnets and distributed denial of service; security for emerging technologies: VoIP, peer-to-peer and cloud computing; encryption and key management; security in software and machine learning; network and system security model; security and privacy in pervasive and ubiquitous computing.

The 9th Australasian Conference on Information Security and Privacy (ACISP 2004) was held in Sydney, 13–15 July, 2004. The conference was sponsored by the Centre for Advanced Computing – Algorithms and Cryptography (ACAC), Information and Networked Security Systems Research (INSS), Macquarie U- versity and the Australian Computer Society. Theaimsoftheconferencearetobringtogetherresearchersandpractitioners working in areas of information security and privacy from universities, industry and government sectors. The conference program covered a range of aspects including cryptography, cryptanalysis, systems and network security. The program committee accepted 41 papers from 195 submissions. The - viewing process took six weeks and each paper was carefully evaluated by at least three members of the program committee. We appreciate the hard work of the members of the program committee and external referees who gave many hours of their valuable time. Of the accepted papers, there were nine from Korea, six from Australia, ?ve each from Japan and the USA, three each from China and Singapore, two each from Canada and Switzerland, and one each from Belgium, France, Germany, Taiwan, The Netherlands and the UK. All the authors, whether or not their papers were accepted, made valued contributions to the conference. In addition to the contributed papers, Dr Arjen Lenstra gave an invited talk, entitled Likely and Unlikely Progress in Factoring. ThisyeartheprogramcommitteeintroducedtheBestStudentPaperAward. The winner of the prize for the Best Student Paper was Yan-Cheng Chang from Harvard University for his paper Single Database Private Information Retrieval with Logarithmic Communication.

ICICS’99, the Second International Conference on Information and C- munication Security, was held in Sydney, Australia, 9-11 November 1999. The conference was sponsored by the Distributed System and Network Security - search Unit, University of Western Sydney, Nepean, the Australian Computer Society, IEEE Computer Chapter (NSW), and Harvey World Travel. I am g- teful to all these organizations for their support of the conference. The conference brought together researchers, designers, implementors and users of information security systems and technologies. A range of aspects was addressed from security theory and modeling to system and protocol designs and implementations to applications and management. The conference con- sted of a series of refereed technical papers and invited technical presentations. The program committee invited two distinguished key note speakers. The ?rst keynote speech by Doug McGowan, a Senior Manager from Hewlett-Packard, USA, discussed cryptography in an international setting. Doug described the current status of international cryptography and explored possible future trends and new technologies. The second keynote speech was delivered by Sushil Ja- dia of George Mason University, USA. Sushil’s talk addressed the protection of critical information systems. He discussed issues and methods for survivability of systems under malicious attacks and proposed a fault-tolerance based - proach. The conference also hosted a panel on the currently much debated topic of Internet censorship. The panel addressed the issue of censorship from various viewpoints namely legal, industrial, governmental and technical.

These proceedings contain the papers of IFIP/SEC 2010. It was a special honour and privilege to chair the Program Committee and prepare the proceedings for this conf- ence, which is the 25th in a series of well-established international conferences on security and privacy organized annually by Technical Committee 11 (TC-11) of IFIP. Moreover, in 2010 it is part of the IFIP World Computer Congress 2010 celebrating both the Golden Jubilee of IFIP (founded in 1960) and the Silver Jubilee of the SEC conference in the exciting city of Brisbane, Australia, during September 20–23. The call for papers went out with the challenging motto of “Security & Privacy Silver Linings in the Cloud” building a bridge between the long standing issues of security and privacy and the most recent developments in information and commu- cation technology. It attracted 102 submissions. All of them were evaluated on the basis of their significance, novelty, and technical quality by at least five member of the Program Committee. The Program Committee meeting was held electronically over a period of a week. Of the papers submitted, 25 were selected for presentation at the conference; the acceptance rate was therefore as low as 24. 5% making SEC 2010 a highly competitive forum. One of those 25 submissions could unfortunately not be included in the proceedings, as none of its authors registered in time to present the paper at the conference.
