Loong: a new IND-CCA-secure code-based KEM
Liping Wang · 2019
Based on hardness of the rank support learning problem which is as hard as the rank syndrome problem, we introduce a new IND-CPA-secure public-key encryption scheme- Loong.CPAPKE. By applying a variant of the Fujisaki-Okamoto transform to Loong.CPAPKE, a new IND-CCA-secure key encapsulation mechanism (KEM for short) can be constructed. We also make comparison on parameter sets between our scheme and some NIST submissions.
