TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms
Advanced Robotics Research, EarlyView.A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Cryptanalysis of PMACx, PMAC2x, and SIVx
IACR Transactions on Symmetric Cryptology, 2017 At CT-RSA 2017, List and Nandi proposed two variable input length pseudorandom functions (VI-PRFs) called PMACx and PMAC2x, and a deterministic authenticated encryption scheme called SIVx.

ESTATE: A Lightweight and Low Energy Authenticated Encryption Mode
IACR Transactions on Symmetric Cryptology, 2020 NIST has recently initiated a standardization project for efficient lightweight authenticated encryption schemes. SUNDAE, a candidate in this project, achieves optimal state size which results in low circuit overhead on top of the underlying block cipher.

Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression [PDF]
, 2015 International audienceIn typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HEpk(m) to some third-party evaluator Charlie.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Mini-ciphers: a reliable testbed for cryptanalysis? [PDF]
, 2009 This paper reports on higher-order square analysis of the AES cipher. We present experimental results of attack simulations on mini-AES versions with word sizes of 3, 4, 5, 6 and 7 bits and describe the propagation of higher-order Lambda-sets inside some

Advanced Science, EarlyView.This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Provably Quantum-Secure Message Authentication Code [PDF]
, 2022 Die Gefahr von Quantencomputer gegen asymmetrische Kryptographie ist schon lange bekannt. Jedoch wurden die Auswirkungen auf die symmetrische Kryptographie als weniger einschlägig betrachtet. In den letzten Jahren sind mehrere effiziente Quantenangriffee

Comprehensive security analysis of CRAFT
IACR Transactions on Symmetric Cryptology, 2020 CRAFT is a lightweight block cipher, designed to provide efficient protection against differential fault attacks. It is a tweakable cipher that includes 32 rounds to produce a ciphertext from a 64-bit plaintext using a 128-bit key and 64-bit public tweak.
