This book constitutes papers presented during the workshop session titled “CyberSec4Europe - Research to Innovation: Common Research Framework on Security and Privacy� during the Privacy Symposium hosted by Università Ca’ Foscari in Venice, Italy, in April 2022.  The 11 peer-reviewed selected papers present findings, conclusions, research, and recommendations in various security-related areas, from highly technical ones (e.g., software and network security) to law and human-centric ones (e.g., governance and cybersecurity awareness).

This book constitutes the refereed proceedings of the Third European Public Key Infrastructure Workshop: Theory and Practice, EuroPKI 2006, held in Torino, Italy, in June 2006. The 18 revised full papers and 4 short papers presented were carefully reviewed and selected from about 50 submissions. The papers are organized in topical sections on PKI management, authentication, cryptography, applications, and short contributions.

The Communications and Multimedia Security conference (CMS 2003) was - ganized in Torino, Italy, on October 2-3, 2003. CMS 2003 was the seventh IFIP working conference on communications and multimedia security since 1995. - search issues and practical experiences were the topics of interest, with a special focus on the security of advanced technologies, such as wireless and multimedia communications. The book "Advanced Communications and Multimedia Security" contains the 21 articles that were selected by the conference program committee for p- sentation at CMS 2003. The articles address new ideas and experimental eval- tion in several ?elds related to communications and multimedia security, such as cryptography, network security, multimedia data protection, application se- rity, trust management and user privacy. We think that they will be of interest not only to the conference attendees but also to the general public of researchers in the security ?eld. We wish to thank all the participants, organizers, and contributors of the CMS 2003 conference for having made it a success.
