IACR Transactions on Symmetric Cryptology, 2020 We present the family of authenticated encryption schemes SKINNY-AEAD and the family of hashing schemes SKINNY-Hash. All of the schemes employ a member of the SKINNY family of tweakable block ciphers, which was presented at CRYPTO 2016, as the underlying

SAEB: A Lightweight Blockcipher-Based AEAD Mode of Operation
Transactions on Cryptographic Hardware and Embedded Systems, 2018 Lightweight cryptography in computationally constrained devices is actively studied. In contrast to advances of lightweight blockcipher in the last decade, lightweight mode of operation is seemingly not so mature, yet it has large impact in performance ...

Revisiting Leakage-Resilient MACs and Succinctly-Committing AEAD
IACR Transactions on Symmetric CryptologyPseudo-Random Injections (PRIs) have been used in several applications in symmetric-key cryptography, such as in the idealization of Authenticated Encryption with Associated Data (AEAD) schemes, building robust AEAD, and, recently, in converting a ...

TEDT, a Leakage-Resist AEAD Mode for High Physical Security Applications
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We propose TEDT, a new Authenticated Encryption with Associated Data (AEAD) mode leveraging Tweakable Block Ciphers (TBCs). TEDT provides the following features: (i) It offers full leakage-resistance, that is, it limits the exploitability of physical ...

Lightweight AEAD and Hashing using the Sparkle Permutation Family [PDF]
IACR Transactions on Symmetric Cryptology, 2020 We introduce the Sparkle family of permutations operating on 256, 384 and 512 bits. These are combined with the Beetle mode to construct a family of authenticated ciphers, Schwaemm, with security levels ranging from 120 to 250 bits.
