Efficient TCitH-Based Alternatives to SLH-DSA: Cross-Layer ASIC Design of Mirath
A 22nm Mirath ASIC signs 17.8x faster than same-node SLH-DSA while using 58% less area.
Researchers report what they call the first ASIC implementation of Mirath, a TCitH-based post-quantum signature, inside a RISC-V system on a 22nm FD-SOI node. Against an SLH-DSA ASIC in the same technology, the design cuts signing latency by 17.8x and total cell area by 58%. The work targets NIST's search for non-lattice alternatives to hash-based SLH-DSA, alongside standardized ML-DSA and FN-DSA.
