In this letter, a new design of blockwise interleaved ideal low-rank parity-check (BII-LRPC) codes is proposed for a fast cryptographic application. We show that the proposed ideal LRPC codes can be used as a key encapsulation mechanism (KEM) for post-quantum cryptography (PQC). The simulation results show that the KEM constructed from the proposed BII-LRPC codes is faster by 30-70% than the ROLLO-I algorithm, an existing LRPC-based cryptosystem.
