Abstract: We present and analyze the performance of DRANKULA, a McEliece-like cryptosystem implementation using rank metric instead of Hamming distance. Namely, we use the scheme proposed by Loidreau in PQCrypto 2017 using Gabidulin codes. We propose a set of carefully selected parameters and we address several nontrivial issues when porting this scheme into real-world systems as, for example, the generation of errors of a given rank. We provide the pseudo-code of the core algorithms of the cryptosystem. In addition, we also show code optimization when special instructions like Carry-less multiplications are available. Moreover, we argue how to have a practical and side-channel resistant version of the cryptosystem. We integrated the scheme in Open Quantum Safe and benchmarked it against the other schemes implemented there. Our results show that DRANKULA can be a practical alternative to other well-known quantum-safe schemes.
