Overview of the Candidates in the CAESAR Competition for Authenticated Encryption Farzaneh Abed

Abstract. The ongoing CAESAR competition aims at finding authenticated encryption schemes that offer advantages over AES-GCM and are suitable for widespread adoption. At the moment, 50 remaining first-round submissions go through an intensive review, analysis and comparison process. While the cryptographic commu-nity benefits greatly from the manifold different submission designs, their pure number implies a challenging amount of study. As part of a remedy, this paper provides an easy-to-grasp overview over functional aspects, security parameters, and robustness offerings of the CAESAR candidates, clustered by their underlying designs (block-cipher-, stream-cipher-, permutation-/sponge-, compression-function-based, dedicated)
