Rainbow - Digital Signature
It is multivariate public key cryptosystem, and is based on the Oil-Vinegar signature scheme. Overall Rainbow - in its classic form - has a signature length of just 66 bytes. The public key …
Signature Verification T −1 - z ∈ Fn Signature Generation: Given a document d ∈ {0, 1}?, use a hash function H to compute w = H(d) ∈ Fm, compute recursively x = S−1(w) ∈ Fm, y = F−1(x) …
Dec 13, 2022 · The smallest size is 58.1 KB with the Compressed Rainbow 1a which has the signing and verifying times 20-50 times slower than the Standard Rainbow. The cycles/time is …

Rainbow offers very small signatures of only a few hundred bits (only 528 bits=66 bytes for the NIST level I security), which are much shorter than those of other (post-quantum) signature …
In this paper, we propose an efficient variant of Rain-bow that has a shorter secret key (and thus generates sig-natures faster) than the corresponding original Rainbow. In our scheme, we...
the size of the secret key of Rainbow can be reduced. Several variants of Rainbow using sparse secret keys have been proposed, e.g. Enhan ed TTS[5], Matrix-based Rainbow[6], and NT …

Oct 28, 2020 · Next, the key generation, signature generation, and signature verification algorithms of Rainbow are introduced. Algorithm 1 illustrates the steps for the key generation …
The result is a Rainbow-like scheme, which reduces the size of the public key by 62 % and the number of field multiplications needed during the verification process by 30 %.

The post-quantum public keys are long. Is it secure to map …
Jun 5, 2024 · is it a reliable thing to map a SHA512 of Rainbow-1 or GEMMS128 public key to such key, to prevent transfer of such huge keys with every message or file transferred?
