This book seeks to generalize techniques and experiences in designing and analyzing cryptographic schemes for blockchain. It devotes three chapters to review the background and basic knowledge, four chapters to discuss specific types of cryptographic primitive design for blockchain, one chapter to discuss optimization tools and another chapter for blockchain regulation and economies. This book covers the systematic survey of research objects, as well as detailed reviews of cryptographic schemes, lectures and methodologies to practice cryptography.The main findings of this book are summarized as following, first, the practical design and analysis of cryptographic schemes for blockchain can address major problems in blockchain at algorithmic level. Then, some intrinsic deficiencies in some traditional cryptographic primitives, like centralized setup, impractical design, etc, prevent the successful application of these primitives in blockchain. However, huge efforts are being made to make these primitives practical and applicable for researchers. Finally, the formal and rigorous design and analysis of public key cryptographic algorithms is vital to blockchain. Design and Analysis of Cryptographic Algorithms in Blockchain is a useful textbook for graduate students and PhD students, or researches who wish to connect cryptography with blockchain for research and developing projects.

This monograph illustrates important notions in security reductions and essential techniques in security reductions for group-based cryptosystems. Using digital signatures and encryption as examples, the authors explain how to program correct security reductions for those cryptographic primitives. Various schemes are selected and re-proven in this book to demonstrate and exemplify correct security reductions. This book is suitable for researchers and graduate students engaged with public-key cryptography.

The 4th International Conference on Cryptology and Network Security (CANS 2005) was held in Xiamen, Fujian Province, China, December 14-16, 2005. The conference was sponsored by the Fujian Normal University and Fujian Digital Certi?cate Authority Co. Ltd and was organized in cooperation with the Int- national Association for Cryptologic Research (IACR). The ?rst International Workshop on Cryptology and Network Security was in Taipei, Taiwan, 2001. The second one was in San Francisco, California, USA, September 26-28, 2002, and the third in Miami, Florida, USA, September 24-26, 2003. CANS 2005 was the ?rst CANS with proceedings published in the Lecture Notes in Computer Science series by Springer. The Program Committee received 118 submissions, and accepted 28 papers from which 1 withdrew and thus 27 papers were included in the proceedings. The reviewing process took eight weeks, each paper was carefully evaluated by at least three members from the Program Committee. We appreciate the hard work of the members of the ProgramCommittee and external referees who gave manyhoursoftheir valuabletime.Thanksto CarlEllison,GoceJakimoski,Bart Preneel, Yongge Wang, Christopher Wolf and Shouhuai Xu, who acted as the shepherds of 6 papers included in the proceedings.In addition to the contributed papers, there were two invited talks: Wenbo Mao spoke on "Research Issues in Network Security" - a practical viewpoint; and Matt Franklin on "Research Issues in Network Security" - a foundations viewpoint.

Here are the refereed proceedings of the EUC 2006 workshops, held in conjunction with the IFIP International Conference on Embedded and Ubiquitous Computing in Seoul, Korea, August 2006. The book presents 102 revised papers spanning six workshops: network-centric ubiquitous systems (NCUS 2006), security in ubiquitous computing systems (SecUbiq 2006), RFID and ubiquitous sensor networks (USN 2006), trustworthiness, reliability and services in ubiquitous and sensor networks (TRUST 2006), embedded software optimization (ESO 2006), and multimedia solution and assurance in ubiquitous information systems (MSA 2006).

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.

This book constitutes the refereed proceedings of the 5th International Conference on Cryptology and Network Security, CANS 2006, held in Suzhou, China, December 2006. The 26 revised full papers and 2 invited papers cover encryption, authentication and signatures, proxy signatures, cryptanalysis, implementation, steganalysis and watermarking, boolean functions and stream ciphers, intrusion detection, and disponibility and reliability.

This book constitutes the refereed proceedings of the Second Australasian Conference on Information Security and Privacy, ACISP'97, held in Sydney, NSW, Australia, in July 1997.The 20 revised full papers presented were carefully selected for inclusion in the proceedings. The book is divided into sections on security models and access control, network security, secure hardware and implementation issues, cryptographic functions and ciphers, authentication codes and secret sharing systems, cryptanalysis, key escrow, security protocols and key management, and applications.

The 13th Australasian Conference on Information Security and Privacy (ACISP 2008) was held at Wollongong, Australia, during July 7-9, 2008. The conference was sponsored by the Centre for Computer and Information Security of the University of Wollongong and the ResearchNetwork for a Secure Australia. The submission and review process was run using the iChair software, written by Thomas Baigneres and Matthieu Finiasz from EPFL, LASEC, Switzerland. We would like to thank them for letting us use their iChair software. The conferencereceived111submissions, out ofwhich the ProgramComm- tee selected 33 papers for presentation at the conference after a rigorous review process.Thesepapersareincludedintheproceedings.Theacceptedpaperscover a range of topics in information security, including authentication, key m- agement, public key cryptography, privacy, anonymity, secure communication, ciphers, network security, elliptic curves, hash functions, and database security. Theconferenceproceedingscontainrevisedversionsoftheselectedpapers.Since some of them were not checked again for correctness before publication, the - thors bear full responsibility for the contents of their papers.We would like to thank the authors of all papers for submitting their papers to the conference. In addition to the contributed papers, the program comprised three invited talks. The invited speakers were Xavier Boyen (Voltage, USA), Josef Pieprzyk (Macquarie University, Australia) and Nigel Phair (Australian High Tech Crime Centre). We would like to express our thanks to them.
