Authenticated encryption (AE) is a cryptographic construction that simultaneously protects
confidentiality and integrity. A considerable amount of research has been devoted to the …

Along with the rapid development and wide application of information technology, human
society has entered the information era. In this era, people live and work in cyberspace …

With a scheme for robust authenticated-encryption a user can select an arbitrary value λ\! ≥
0 and then encrypt a plaintext of any length into a ciphertext that's λ characters longer. The …

Abstract The National Institute of Standards and Technology (NIST) initiated a public
standardization process to select one or more Authenticated Encryption with Associated …

Abstract We propose the Synthetic Counter-in-Tweak (SCT) mode, which turns a tweakable
block cipher into a nonce-based authenticated encryption scheme (with associated data) …

We present the Deoxys family of authenticated encryption schemes, which consists of
Deoxys-I and Deoxys-II. Both are nonce-based authenticated encryption schemes with …

A common requirement in practice is to periodically rotate the keys used to encrypt stored
data. Systems used by Amazon and Google do so using a hybrid encryption technique …

We study the use of symmetric cryptography in the MTProto 2.0 protocol, Telegram's
equivalent of the TLS record protocol. We give positive and negative results. On the one …

We present practical attacks on OCB2. This mode of operation of a blockcipher was
designed with the aim to provide particularly efficient and provably secure authenticated …

The keyed duplex construction was introduced by Bertoni et al.(SAC 2011) and recently
generalized to full-state absorption by Mennink et al.(ASIACRYPT 2015). We present a …
