The Asian-workshop on Symmetric Key Cryptography (ASK) starts in Singapore in 2011, to promote research on symmetric key cryptography in Asian area. This is an annual workshop, usually held in second half of the year. The program usually contains some invited talks, and working groups for collaborative research works. ASK 2019 will be the 9th workshop, to be held in Kobe, Japan, during 13 - 15 Dec 2019, chaired by Takanori Isobe and Yu Sasaki.
