The uses of technology in education have kindled great interest in recent years. Currently, considerable resources are being expended to connect schools to the Internet, to purchase powerful (and increasingly affordable) computers, and on other implementations of educational technologies. However, the mere availability of powerful, globally-connected computers is not sufficient to insure that students will learn--particularly in subjects that pose considerable conceptual difficulties, such as in science and mathematics. The true challenge is not just to put the newest technologies in our schools, but to identify advanced ways to design and use these new technologies to advance learning. This book offers a "snapshot" of current work that is attempting to address this challenge. It provides valuable and timely information to science and mathematics educators, educational and cognitive researchers, instructional technologists and educational software developers, educational policymakers, and to scholars and students in these fields.

The 16th Workshop on Selected Areas in Cryptography (SAC 2009) was held at the University of Calgary,in Calgary, Alberta, Canada, during August 13-14, 2009. There were 74 participants from 19 countries. Previous workshops in this series were held at Queens University in Kingston (1994, 1996, 1998, 1999, and 2005), Carleton University in Ottawa (1995, 1997, and 2003), University of - terloo (2000 and 2004), Fields Institute in Toronto (2001), Memorial University of Newfoundland in St. Johns (2002), Concordia University in Montreal (2006), University of Ottawa (2007), and Mount Allison University in Sackville (2008). The themes for SAC 2009 were: 1. Design and analysis of symmetric key primitives and cryptosystems, incl- ing block and stream ciphers, hash functions, and MAC algorithms 2. E?cient implementations of symmetric and public key algorithms 3. Mathematical and algorithmic aspects of applied cryptology 4. Privacy enhancing cryptographic systems This included the traditional themes (the ?rst three) together with a special theme for 2009 workshop (fourth theme).

This book contains revised selected papers from the 27th International Conference on Selected Areas in Cryptography, SAC 2020, held in Halifax, Nova Scotia, Canada in October 2020. The 27 full papers presented in this volume were carefully reviewed and selected from 52 submissions. They cover the following research areas: design and analysis of symmetric key primitives and cryptosystems, including block and stream ciphers, hash functions, MAC algorithms, and authenticated encryption schemes, efficient implementations of symmetric and public key algorithms, mathematical and algorithmic aspects of applied cryptology, and secure elections and related cryptographic constructions
