On the optimality of individual entangling-probe attacks against BB84 quantum key distribution
, 2007 It is shown that an existing method to study ideal individual attacks on the BB84 QKD protocol using error discard can be adapted to reconciliation with error correction, and that an optimal attack can be explicitly found.

Controlled Formation of Skyrmion Bags
Advanced Materials, EarlyView.This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

A second pre-image attack and a collision attack to cryptographic hash function lux
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2017 Cryptography is a science that provides the security of information in communication. One of the most important sub-branches of cryptography is the hash functions. Hash functions are known as the digital fingerprints. Following the recent attacks on the widely used hash functions MD5 and SHA-1 and the increase in computational power, the need for a new

Fault Attack of SMS4 Based on Internal Collisions
Journal of Physics: Conference Series, 2020 Abstract A fault attack of SMS4 based on internal collision is proposed. The method assumes that the attacker can attack under the condition of selecting plaintext, and adopts the byte-oriented random fault model to successfully recover the original key by injecting the fault in the first few rounds of the encryption algorithm of the ...
