A new type of signature scheme, called NTRUSign, based on solving the approximately closest vector problem in a NTRU lattice was proposed at CT-RSA’03. However no security proof ...
Key exposures, known or inconspicuous, are a real security threat. Recovery mechanisms from such exposures are required. For digital signatures such a recovery should ideally —an...
We present the first signature scheme which is “short”, stateless and secure under the RSA assumption in the standard model. Prior short, standard model signatures in the RSA...
In ProvSec 2008, Wu et al. constructed two server-aided verification signature (SAV-) schemes based on BLS signature. In this paper, we provide a new definition of the security of...
Verifiable Signature Sharing (VS ) enables the recipient of a digital signature, who is not necessarily the original signer, to share such signature among n proxies so that a subse...
