Selected Areas in Cryptography (SAC) is an international
cryptography conference (originally a workshop) held every August in
Canada since 1994. The first workshop was organized by
Carlisle Adams, Henk Meijer,
Stafford Tavares and
Paul van Oorschot. Through 1999, SAC was hosted at either
Queen's University or
Carleton University, but starting in 2000, locations have ranged across Canada. SAC has featured research presentations on many cryptographic topics, with a traditional focus on the design and
analysis of
block ciphers. SAC is regarded as a high-quality venue for presenting cryptographic results, and is the only cryptography conference held annually in Canada. Since 2003, SAC has included an invited lecture called the Stafford Tavares Lecture, in honor of one of its original organizers and strongest supporters.
