Side-channel analysis (SCA) and implementation attacks have become an important field of research at universities and in the industry. In order to enhance the resistance of cryptographic and security critical implementations within the design phase, constructive attacks and analyzing techniques may serve as a quality metric to optimize the design and development process. Since 2010, COSADE provides an international platform for researchers, academics, and industry participants to present their work and their current research topics. It is an excellent opportunity to exchange on new results with international experts and to initiate new collaborations and information exchange at a professional level. The workshop will feature both invited presentations and contributed talks.
