The papers are organized in topical sections on system security, Web security and worm detection, cloud storage security, virtualization for cloud computing, trusted and trustworthy computing, authentication and security protocols, intrusion detection and recovery, side channel attacks and defense, engineering issues of crypto, cryptanalysis, attribute-based encryption, and cryptographic primitives and applications.

IFIP/SEC2000, being part of the 16th IFIP World Computer Congress (WCC2000), is being held in Beijing, China from August 21 to 25, 2000. SEC2000 is the annual conference of TCll (Information Security) of the International Federation of Information Processing. The conference focuses on the seamless integration of information security services as an integral part of the Global Information Infrastructure in the new millenniUm. SEC2000 is sponsored by the China Computer Federation (CCF), IFIP/TCll, and Engineering Research Centre for Information Security Technology, Chinese Academy of Sciences (ERCIST, CAS). There were 180 papers submitted for inclusion, 50 papers among them have been accepted as long papers and included in this proceeding, 81 papers have been accepted as short papers and published in another proceeding. All papers presented in this conference were reviewed blindly by a minimum of two international reviewers. The authors' affiliations of the 180 submissions and the accepted 131 papers range over 26 and 25 countries or regions, respectively. We would like to appreciate all who have submitted papers to IFIP/SEC2000, and the authors of accepted papers for their on-time preparation of camera-ready fmal versions. Without their contribution there would be no conference. We wish to express our gratitude to all program committee members and other reviewers for their hard work in reviewing the papers in a short time and for contributing to the conference in different ways. We would like to thank Rein Venter for his time and expertise in compiling the fmal version of the proceedings.

The11thInternationalConferenceonInformationandCommunicationsSecurity (ICICS 2009) was held in Beijing, China during December 14-17, 2009. The ICICS conferenceseriesis anestablished forum that bringstogether people from universities,researchinstitutes, industry and governmentinstitutions, who work in a range of ?elds within information and communications security. The ICICS conferencesgiveattendeestheopportunitytoexchangenewideasandinvestigate developments in the state of the art. In previous years, ICICS has taken place in the UK (2008), China (2007, 2005, 2003, 2001 and 1997), USA (2006), Spain (2004), Singapore (2002), and Australia (1999). On each occasion, as on this one, the proceedings have been published in the Springer LNCS series. In total, 162 manuscripts from 20 countries and districts were submitted to ICICS 2009, and a total of 37 (31 regular papers plus 6 short papers) from 13 countries and districts were accepted (an acceptance rate of 23%). The accepted papers cover a wide range of disciplines within information security and applied cryptography. Each submission to ICICS 2009 was anonymously reviewed by three or four reviewers. We are very grateful to members of the Program C- mittee, which was composed of 44 members from 14 countries; we would like to thank them, as well as all the external referees, for their time and their valuable contributions to the tough and time-consuming reviewing process.
