The novelty of Dilithium over the previous schemes is that we also shrink the size of the public key by a factor of 2.5 at the expense of increasing the signature by around 150 bytes. For 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 …

“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]

On top of this, Dilithium introduced compression of the public key as well, achieving about a 60% smaller public key than previous schemes with only a slight increase in the size of the digital …

Feb 16, 2021 · Dilithium improves on the most efficient scheme that only uses the uniform distribution, due to Bai and Galbraith, by using a new technique that shrinks the public key by …

Since in many applications, the total sum of the public key size and the signature length is important, we believe that this is a very good trade-of. In fact, the total size of the public key …

The CRYSTALS-Dilithium Digital Signature Algorithm is a member of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) suite of algorithms. The strength of a CRYSTALS …

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

We can then see that we have a 2,560 byte private key, a 1,344 byte public key and a 2,484 byte signature length. With Dilithium2 on its own, these would be 2,528 bytes, 1,312 bytes and …

As discussed in Section 1.2, the main design improvement of Dilithium over the scheme in Fig. 1 is that the public key size is approximately halved at the expense of fewer than a hundred …
