Waveform dissimilarity factor-based protection for main transformers in wind farms
Energy Reports, 2023 Current differential protection (CDP) is widely used as main protection for transformers due to its high reliability and selectivity. Owing to non-fundamental frequency current, magnetizing inrush and current transformer (CT) saturation, CDP may undergo ...

A Fault Attack on the Family of Enocoro Stream Ciphers
Cryptography, 2021 A differential fault attack framework for the Enocoro family of stream ciphers is presented. We only require that the attacker can reset the internal state and inject a random byte-fault, in a random register, during a known time period.
