Towards Lightweight Side-Channel Security and the Leakage-Resilience of the Duplex Sponge
Authenticated Encryption Duplex Construction Leakage-Resilience
2019/3/1
Authenticated Encryption (AE) has become the de facto standard for encryption in modern protocols, and the ubiquitous deployment of small connected devices naturally calls for the availability of ligh...
Side-channel attacks, especially differential power analysis (DPA), pose a serious threat to cryptographic implementations deployed in a malicious environment. One way to counter side-channel attacks ...
Key-dependent cube attack on reduced Frit permutation in Duplex-AE modes
Frit Duplex authenticated encryption mode Key-dependent cube attack
2019/2/25
Frit is a new lightweight 384-bit cryptographic permutation proposed by Simon et al., which is designed for resisting fault injection and performs competitively in both hardware and software. Dobrauni...
Full-State Keyed Duplex With Built-In Multi-User Support
Duplex construction full-state distinguishing bounds
2017/6/2
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 generalization of the full-st...
Security of Full-State Keyed Sponge and Duplex: Applications to Authenticated Encryption
Sponge construction Duplex construction full-state absorption
2015/12/30
We provide a security analysis for full-state keyed Sponge and full-state Duplex
constructions. Our results can be used for making a large class of Sponge-based authenticated
encryption schemes more...
Parallel authenticated encryption with the duplex construction
duplex construction authenticated encryption
2014/3/7
The authentication encryption (AE) scheme based on the duplex construction can no be paralellized at the algorithmic level. To be competitive with some block cipher based modes like OCB (Offset CodeBo...
