The Second Asian Workshop on Symmetric Key Cryptography - ASK 2012

About ASK 2012

ASK has been held to promote research on symmetric key cryptography (block ciphers, stream ciphers, hash functions, analysis, designs, proofs and implementations of these primitives etc) in Asia since 2011. ASK 2012 will be held inside the Nagoya University Campus, Japan on August 27, 28 and 29, 2012. The program will contain mainly two parts, invited talks and group discussions. ASK 2012 targets mainly for active students and young researchers to learn and work in small interest groups.

Interested Asian-based (including Australia) researchers are welcome to contact us for participation. We also welcome researchers outside Asia to contact us (the precedence will be given to Asian-based researchers if the number of participants exceeds the capacity). A limited number of stipend for plane ticket may be available for PhD students who have difficulty obtaining funding.
