With the urgency of the threat imposed by quantum computers, there is a strong interest in making the signature schemes quantum resistant. As the promising candidates to ensure post-quantum security, symmetric-key primitives, in particular the recent MPC/FHE/ZK-friendly hash functions or block ciphe...
