2021年 暗号と情報セキュリティワークショップ
(Workshop on Cryptography and Information Security 2021, WCIS 2021)

概要

暗号と情報セキュリティワークショップ(WCIS)は、国内の情報セキュリティ研究の活性化を目的として、 3大IACR カンファレンス (CRYPTO, EUROCRYPT, ASIACRYPT) や4大セキュリティ会議 (ACM CCS, IEEE S&P, Usenix Security, NDSS) 採録論文を中心に先進的な研究を日本国内で紹介して頂く招待講演を中心としたイベントです。 2018年以前にISEC研究専門委員会によって5月、9月、12月の研究会内で実施していた3大IACR カンファレンス発表論文に関する招待講演の後継となるイベントであり、 暗号と情報セキュリティシンポジウム(SCIS)のプレイベントとして2019年より年に1回の頻度で実施しています。
