This book constitutes the refereed proceedings of the International Conference on Trusted Systems, INTRUST 2012, held in London, UK, in December 2012. The 6 revised full papers presented together with 3 short invited papers and a short paper which formed the basis for a panel session were carefully reviewed and selected from 19 submissions. The papers are organized in topical section on automated analysis, security and trust, mobile trust, security of distributed systems, evaluation and analysis, and embedded security.

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.

This volume contains the 12 papers presented at the WISTP 2009 conference, held in Brussels, Belgium in September 2009. WISTP 2009 was the third int- national workshop devoted to information security theory and practice. WISTP 2009 built on the successful WISTP 2007 and 2008 conferences, held in Heraklion, Crete, Greece and Seville, Spain in May 2007 and May 2008, - spectively. The proceedings of WISTP 2007 and WISTP 2008 were published as volumes 4462 and 5019 of the Lecture Notes in Computer Science series. This workshop received the following support: - Co-sponsored by IFIP WG 11. 2 Small System Security - Co-sponsored by VDE ITG - Technical sponsorship of the IEEE Systems, Man & Cybernetics Society - Supported by the Technical Committee on Systems Safety and Security - Organized in cooperation with the ACM SIGSAC - Supported by ENISA - Supported by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) These proceedings contain 12 original papers covering a range of theoretical and practical topics in information security. For the purposes of the organi- tion of the WISTP program, the papers were divided into four main categories, namely: - Mobility - Attacks and Secure Implementations - Performance and Security - Cryptography The12papersincludedherewereselectedfromatotalof27submissions. The refereeing process was rigorous,involving at least three (and mostly four or ?ve) independent reports being prepared for each submission.

This book constitutes the refereed proceedings of the 18th International Conference on Information Security, ISC 2015, held in Trondheim, Norway, in September 2015. The 30 revised full papers presented were carefully reviewed and selected from 103 submissions. The papers cover a wide range of topics in the area of cryptography and cryptanalysis and are organized in the following topical sections: signatures; system and software security; block ciphers; protocols; network and cloud security; encryption and fundamentals; PUFs and implementation security; and key generation, biometrics and image security.

Thisvolumecontainsthe15paperspresentedinthetechnicalstrandoftheTrust 2009 conference, held in Oxford, UK in April 2009. Trust 2009 was the second international conference devoted to the technical and socio-economic aspects of trusted computing. The conference had two main strands, one devoted to technical aspects of trusted computing (addressed by these proceedings), and the other devoted to socio-economic aspects. Trust 2009 built on the successful Trust 2008 conference, held in Villach, Austria in March 2008. The proceedings of Trust 2008, containing 14 papers, were published in volume 4968 of the Lecture Notes in Computer Science series. ThetechnicalstrandofTrust2009contained15originalpapersonthedesign and application of trusted computing. For these proceedings the papers have been divided into four main categories, namely: - Implementation of trusted computing - Attestation - PKI for trusted computing - Applications of trusted computing The 15 papers included here were selected from a total of 33 submissions. The refereeing process was rigorous, involving at least three (and mostly more) independent reports being prepared for each submission. We are very grateful to our hard-working and distinguished Program Committee for doing such an excellent job in a timely fashion. We believe that the result is a high-quality set of papers, some of which have been signi?cantly improved as a result of the refereeing process. We would also like to thank all the authors who submitted their papers to the technical strand of the Trust 2009 conference, all external referees, and all the attendees of the conference.

Over the last two decades, mobile telecommunications has grown dramatically, from a small niche technology to a massive industry. Mobile telephones are now ubiquitous, and the divisions between PCs, PDAs, mobile telephones and other mobile devices are becoming increasingly blurred. Against this background, the security of information of both the devices themselves, and the information handled by these devices, is becoming ever more important. Security for Mobility pulls together up to the minute research from an international group of academics and professionals working in industry. The main text of the book is divided into five parts - underlying technologies; network security; mobile code issues; application security; and the future. Each chapter of the book is the collaboration of different authors, including many of the leading European experts currently working within the field. Thus each chapter is self-contained and can be read independently, although there are many relationships between the various chapters. The book will be of interest to engineers and computer scientists working in security-related aspects of the communications, computing and telecommunications industries, as well as postgraduate students and academics working within these fields.
