Welcome to SAFECOMP 2006, the 25th International Conference on Computer Safety, Security and Reliability, held in Gdansk,Poland. Since it was established in 1979 by the European Workshop on Industrial Computer Systems, Technical Committee 7 on Safety, Reliability and Security (EWICS TC7), SAFECOMP has continuously contributed to the progress in high integrity applications of information technologies. The conference focuses on the state of the art, expe- ence and new trends in the areas of safety, security and reliability of critical IT systems and applications and serves as a platform for knowledge and technology transfer for researchers, industry (suppliers, operators, users), regulators and certi?ers of such systems. SAFECOMP provides ample opportunity to exchange insights and experiences on emerging methods, approaches and practical so- tions to safety, security and reliability problems across the borders of di?erent application domains and technologies. The SAFECOMP 2006 program re?ected in this book included 32 papers selected from 101 submissions of full texts. The submissions came from authors representing 26 di?erent countries from Europe, Asia, and North and South America. The 32 accepted papers were prepared by experts representing 14 d- ferent countries. The above data con?rm the broad and increasing interest in SAFECOMP and the topics addressed. The program was supplemented by three keynote presentations by outsta- ing invited experts (not included in this book). The keynotes focused on - terdisciplinary aspects of dependability of computer systems, practical aspects of application of safety standards and new challenges of information security research and development.
