Threshold cryptosystems and signature schemes give ways to distribute trust throughout a group and increase the availability of cryptographic systems. A standard approach in design...
Abstract. A proxy signature scheme allows an entity to delegate his/her signing capability to another entity in such a way that the latter can sign messages on behalf of the former...

In this paper, we present a novel protocol, called Distributed Signcryption with Verifiable Partial Signature (DiSigncryption) protocol, to allow an agent owner to securely distrib...
In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar’s code-based solution to use the short integer solution (SIS) problem as securi...

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...
