Security of signed ELGamal encryption [PDF]
, 2005 Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against the adaptive chosen ciphertext attack, in which an attacker can freely use

Efficient public-key cryptography with bounded leakage and tamper resilience [PDF]
, 2016 We revisit the question of constructing public-key encryption and signature schemes with security in the presence of bounded leakage and tampering memory attacks.

Multiset-Algebraic Cryptanalysis of Reduced Kuznyechik, Khazad, and secret SPNs
IACR Transactions on Symmetric Cryptology, 2017 We devise the first closed formula for the number of rounds of a blockcipher with secret components so that these components can be revealed using multiset, algebraic-degree, or division-integral properties, which in this case are equivalent.

Online Template Attacks: Revisited
Transactions on Cryptographic Hardware and Embedded Systems, 2021 An online template attack (OTA) is a powerful technique previously used to attack elliptic curve scalar multiplication algorithms. This attack has only been analyzed in the realm of power consumption and EM side channels, where the signals leak related ...

Model-Based Generation of Attack-Fault Trees
, 2023 Joint safety and security analysis of cyber-physical systems is a necessary step to correctly capture inter-dependencies between these properties. Attack-Fault Trees represent a combination of dynamic Fault Trees and Attack Trees and can be used to model and model-check a holistic view on both safety and security.

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Advanced Science, EarlyView.This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

Differential Attacks on Generalized Feistel Schemes [PDF]
, 2013 While generic attacks on classical Feistel schemes and unbalanced Feistel schemes have been studied a lot, generic attacks on several generalized Feistel schemes like type-1, type-2 and type-3 and alternating Feistel schemes, as defined in [8], have not been systematically investigated.
