Abstract
The present document proposes Qameleon, a new Authenࢼcated Encrypࢼon with Associated Data (AEAD) design based on well-understood technologies. Parameters sets and variants are suggested that can use different key and tweak sizes, and for each of them specific security levels are claimed. Qameleon targets low-latency scenarios, such as memory encrypঞon. This suggests that the scheme is
“perfectly” parallelisable, i.e., as parallelisable as possible on a single task. In particular, we support decrypঞon of any block (while authenঞcaঞon is sঞll taking place). Moreover, as our main focus is memory nencrypঞon, we mostly target scenarios in which the nonce are not repeated.
