Beyond Birthday Bound Secure MAC in Faulty Nonce Model
Graceful Security Faulty Nonce Mirror Theory
2019/2/27
Encrypt-then-MAC (EtM) is a popular mode for authenticated encryption (AE). Unfortunately, almost all designs following the EtM paradigm, including the AE suites for TLS, are vulnerable against nonce ...
Generic Attacks against Beyond-Birthday-Bound MACs
Modes of operation Cryptanalysis Message Authentication Codes
2018/6/5
In this work, we study the security of several recent MAC constructions with provable security beyond the birthday bound. We consider block-cipher based constructions with a double-block internal stat...
The international standard ISO/IEC 9797-1:2011 specifies six versions of MACs, called MAC Algorithm 1-6, and many of these MACs enjoy widespread use in practical applications. However, security guaran...
Efficient Beyond-Birthday-Bound-Secure Deterministic Authenticated Encryption with Minimal Stretch
deterministic authenticated encryption symmetric cryptography cryptographic schemes
2016/4/22
Block-cipher-based authenticated encryption has obtained considerable attention from the ongoing CAESAR competition. While the focus of CAESAR resides primarily on nonce-based authenticated encryption...
Beyond-Birthday-Bound Security for Tweakable Even-Mansour Ciphers with Linear Tweak and Key Mixing
tweakable block cipher iterated Even-Mansour cipher key-alternating cipher
2015/12/23
The iterated Even-Mansour construction defines a block cipher from a tuple of public $n$-bit permutations $(P_1,\ldots,P_r)$ by alternatively xoring some $n$-bit round key $k_i$, $i=0,\ldots,r$, and a...
In CRYPTO 1999, J. An and M. Bellare proposed a MerkleDamgⅹard
iteration based MAC construction called NI-MAC in order to
avoid constant re-keying on multiblock messages in NMAC and to ease
the sec...
