Outline of Final Research Achievements

We studied authenticated encryption, a symmetric key primitive for privacy and authenticity. As our main results, we analyzed the security of various authenticated encryption schemes including GCM, CLOC, and SILC. We also studied the security of a block cipher called SIMON. We designed a message authentication scheme based on a tweakable block cipher. Finally, we contributed to the international competition called CAESAER, and organized international conferences DIAC 2016 and ASK 2016. Our proposal to CAESAR, CLOC and SILC, were not selected as the final round candidates.
