An improvement of nonrepudiable threshold proxy signature scheme with known signers
In a (t, n) threshold proxy signature scheme, which is a variant of the proxy signature scheme, the proxy signature key is shared among a group of n proxy signers delegated by the ...

Revisiting Fully Distributed Proxy Signature Schemes
In a proxy signature scheme, a potential signer delegates his capabilities to a proxy signer, who can sign documents on behalf of him. The recipient of the signature verifies both...
