Invertible Quadratic Non-Linear Layers for MPC-/FHE-/ZK-Friendly Schemes over Fnp
IACR Transactions on Symmetric Cryptology, 2022 Motivated by new applications such as secure Multi-Party Computation (MPC), Fully Homomorphic Encryption (FHE), and Zero-Knowledge proofs (ZK), many MPC-, FHE- and ZK-friendly symmetric-key primitives that minimize the number of multiplications over Fp ...

State Complexity of Multiple Catenations
Fundamenta Informaticae, 2018 We improve some results relative to the state complexity of the multiple catenations described by Gao and Yu. In particular we nearly divide by 2 the size of the alphabet needed for witnesses. We also give some refinements to the algebraic expression of the state complexity, which is especially complex with this operation.

The multiplicative complexity of interval checking
IACR Cryptol. ePrint Arch., 2022 We determine the exact AND-gate cost of checking if $a\leq x < b$, where $a$ and $b$ are constant integers. Perhaps surprisingly, we find that the cost of interval checking never exceeds that of a single comparison and, in some cases, it is even lower.

A Tool for Lightweight (AND, XOR) Implementations of Large-Degree S-boxes
Transactions on Cryptographic Hardware and Embedded SystemsWe propose a new ad hoc automatic tool to look for lightweight implementations of non-linear functions on up to 7 variables. This tool is mainly aimed at finding implementations of arbitrary cryptographic S-boxes, with the goal of enabling lightweight ...

Multiple faces of the SAGA complex [PDF]
Current Opinion in Cell Biology, 2010 The SAGA complex provides a paradigm for multisubunit histone modifying complexes. Although first characterized as a histone acetyltransferase, because of the Gcn5 subunit, SAGA is now known to contain a second activity, a histone deubiquitinase, as well as subunits important for interactions with transcriptional activators and the general ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation
Molecular Oncology, EarlyView.How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.
