Cryptography in Chinese consists of two characters meaning "secret coded". Thanks to Ch'in Chiu-Shao and his successors, the Chinese Remainder Theorem became a cornerstone of public key cryptography. Today, as we observe the constant usage of high-speed computers interconnected via the Internet, we realize that cryptography and its related applications have developed far beyond "secret coding". China, which is rapidly developing in all areas of technology, is also writing a new page of history in cryptography. As more and more Chinese become recognized as leading researchers in a variety of topics in cryptography, it is not surprising that many of them are Professor Xiao's former students. Progress on Cryptography: 25 Years of Cryptography in China is a compilation of papers presented at an international workshop in conjunction with the ChinaCrypt, 2004. After 20 years, the research interests of the group have extended to a variety of areas in cryptography. This edited volume includes 32 contributed chapters. The material will cover a range of topics, from mathematical results of cryptography to practical applications. This book also includes a sample of research, conducted by Professor Xiao's former and current students. Progress on Cryptography: 25 Years of Cryptography in China is designed for a professional audience, composed of researchers and practitioners in industry. This book is also suitable as a secondary text for graduate-level students in computer science, mathematics and engineering.

Thesecondinternationalconferenceonprovablesecurity, ProvSec2008, washeld in Shanghai, China, during October 30th - November 1st, 2008. The conference wassponsoredbyShanghaiJiaoTongUniversity(SJTU)incooperationwiththe Chinese Association for Cryptologic Research (CACR) and the Natural Science Foundation of China (NSFC). The aim of ProvSec is to provide a platform for researchers, scholars, and practitionerstoexchangeideasandextendknowledgeonprovablesecurity, which is an important research area in cryptography. The ?rst ProvSec was held in Wollongong, Australia, in 2007. This year, the conference received 79 papers and the program committee selected 25 papers during eight weeks' thorough reviewing process. The authors ofthe selected papersarefrom12 di?erentcountries: Australia, Belgium, China, Estonia, France, Germany, India, Japan, Norway, Singapore, the UK, and the USA. We are grateful to the members of the program committee for their many hours of valuable time and hard work. In addition to the regular conference program, the conference hosted two invited talks: - Kenny Paterson (University of London, Royal Holloway): Non-interactive Key Distribution and Identity-Based Encryption: A Historical Perspective - PhillipRogaway(University ofCalifornia, Davis): BlockcipherModes of- eration: Culture and Counter-Culture in Modern Cryptography. The conference was also one of the special events for the 50th anniversary of the Department of Computer Science at SJTU. We extend our gratitude to all the people involved in organizing ProvSec from the Department of Computer Science and Engineering and the Lab for InformationSecurityofShanghaiJiaoTongUniversity, inparticulartoYuLong, Yanfei Zheng, Meiju Chen, Zhihua Su, and Bo Zhu for their great e?orts in making the conference run smoot

"Cryptographic Protocol: Security Analysis Based on Trusted Freshness" mainly discusses how to analyze and design cryptographic protocols based on the idea of system engineering and that of the trusted freshness component. A novel freshness principle based on the trusted freshness component is presented; this principle is the basis for an efficient and easy method for analyzing the security of cryptographic protocols. The reasoning results of the new approach, when compared with the security conditions, can either establish the correctness of a cryptographic protocol when the protocol is in fact correct, or identify the absence of the security properties, which leads the structure to construct attacks directly. Furthermore, based on the freshness principle, a belief multiset formalism is presented. This formalism s efficiency, rigorousness, and the possibility of its automation are also presented.
The book is intended for researchers, engineers, and graduate students in the fields of communication, computer science and cryptography, and will be especially useful for engineers who need to analyze cryptographic protocols in the real world.
Dr. Ling Dong is a senior engineer in the network construction and information security field. Dr. Kefei Chen is a Professor at the Department of Computer Science and Engineering, Shanghai Jiao Tong University.
