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

We propose a new mode of operation called ZMAC allowing to construct a (stateless and
deterministic) message authentication code (MAC) from a tweakable block cipher (TBC) …

This paper proposes an authenticated encryption scheme, called SIVx, that preserves BBB
security also in the case of unlimited nonce reuses. For this purpose, we propose a single …

The Galois/Counter Mode of operation (GCM) is a widely used nonce‐based authenticated
encryption with associated data mode which provides the birthday‐bound security in the …

DCT is a beyond-birthday-bound~(BBB) deterministic authenticated encryption~(DAE) mode
proposed by Forler et al. in ACISP 2016, ensuring integrity by redundancy. The instantiation …

An ongoing research challenge in symmetric cryptography is to design an authenticated
encryption (AE) with a commitment to the secret key or preferably to the entire context. One …

We cryptanalyze several symmetric encryption and hashing algorithms. A central factor in
the security of symmetric cryptographic algorithms is the resistance of their core building …

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

With the rise of big data, it is still an open problem to securely store and process large
amounts of data on lightweight devices. This paper focuses on the data security protection in …

Abstract Modern Cryptography. Modern cryptography has become an often ubiquitous but
essential part of our daily lives. Protocols for secure authentication and encryption protect …
