Since many applications require the transmission of both the public key and the signature (e.g. certificate chains), we designed our scheme to minimize the sum of these parameters.

“Dilithium uses only uniform sampling, and is in general much easier to implement than Falcon; on the other hand, Falcon produces much shorter signatures“ [Pornin, 2019]

Two optimisations are made to the public key, which is traditionally (A, t), to reduce its size. The first optimisation, the most natural, consists of transmitting only the seed used to generate the matrix A.

Aug 24, 2023 · The size of the private key for Dilithium types is by 256 bits larger. This is due to the enlargement of the size of the hash of the public key referenced as tr, which was not taken into …

Feb 8, 2021 · To harmonize the randomness expansion function in the key generation and signing, we are now using SHAKE-256 with 512-bit secret seeds for both. We also reduced the output size of the …

CRYSTALS Dilithium uses lattice-based Fiat-Shamir schemes, and produces one of the smallest signatures of all the post-quantum methods, and with relatively small public and private key sizes. …

Feb 16, 2021 · The table below gives an indication of the performance of the Dilithium with all the updates we applied to the parameter sets for round-3 of the NIST PQC project.

Oct 23, 2022 · This proposal addresses aspects of key identification, key serialization, and key compression for the future primary NIST PQC Digital Signature standard, CRYSTALS-Dilithium.

Parameters for CRYSTALS-Dilithium ( > 128-bit quantum security) ... Public key generation / verification: > 10,000 per second Signing : > 3,000 per second
