In threshold ring signature schemes, any group of t entities spontaneously conscript arbitrarily n - t entities to generate a publicly verifiable t-out-of-n signature on behalf of ...

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...

The notion of concurrent signatures was recently introduced by Chen, Kudla and Paterson. In concurrent signature schemes, two entities can produce two signatures that are not bindi...
In 2004, Abe et al. proposed a threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme, and it allows the ...
Abstract. Delegation of rights is a common practice in the real world. We present two identitybased threshold proxy signature schemes, which allow an original signer to delegate he...
