Analysis of Layered ROLLO-I

ePrint Report: Analysis of Layered ROLLO-I

Seongtaek Chee, Kyung Chul Jeong, Tanja Lange, Nari Lee, Alex Pellegrini, Hansol Ryu

We analyse Layered ROLLO-I, a code-based cryptosystem submitted to the Korean post quantum cryptography competition, of which four versions have been proposed. We show that the first two versions do not provide the claimed security against rank decoding attacks and give reductions to small instances of ROLLO-I for which such attacks are even more effective. Finally, we provide two efficient message …
