For avoding the attacks from quantum computing (QC), this study applies the post-quantum cryptography (PQC) methods without hidden subgroups to the security of vehicular communications. Due the mainstream technologies of PQC methods (i.e. lattice-based cryptography methods), the standard digital signature methods including Dilithium and Falcon have been discussed and compared. This study uses a queueing model to analyze the performance of these standard digital signature methods for selection decision-making.
