Abstract
Enocoro-80 is a lightweight stream cipher proposed in 2007. Several attacks on it have been published, although none have violated the claimed 80-bit security of Enocoro-80. The cipher had been adopted as an ISO/IEC29192 standard in 2012. This paper exploits the slide property of Enocoro-80, and shows that it is vulnerable to a related-key chosen IV attack when the key belongs to a large subset of 272272 of all 280280 keys. This attack has a time complexity of 248248, requiring 217217 chosen IVs. This is the first paper pointing out a potential weakness in the Enocoro-80 stream cipher.
