CAESAR and NORX

Developing the Future of Authenticated Encryption

Philipp Jovanovic and aumasson

"Nearly all of the symmetric encryption modes you learned about in school, textbooks, and Wikipedia are (potentially) insecure." -- Matthew Green

In recent history, we saw time and again (to some extent catastrophic) failures of cryptographic constructions for authenticated encryption (AE) due to bad design choices, implementation errors and a lack of reliable standards. After an introduction providing some background information on these topics, we present CAESAR, a new cryptographic competition which aims to find solutions to the problems mentioned above. In the second part of the talk, we introduce NORX, a new and next-generation AE scheme and our candidate for CAESAR.
