In some practical circumstances, the ability of a signer should be restricted. In group signature schemes, a group member may be allowed to generate signatures up to a certain numb...

We propose a threshold RSA scheme which is as efficient as the fastest previous threshold RSA scheme (by Shoup), but where two assumptions needed in Shoup’s and in previous schem...
To enhance applications of smart cards, Miyazaki and Takaragi proposed a (t, n) threshold digital signature scheme based on the security of elliptic curve discrete logarithm (ECDL...
Based on the factorization problem, a modified (t, n) threshold group-oriented scheme with message recovery is proposed. In the proposed scheme, any combination of more than t mem...
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...
