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 ...

A Secure Nonrepudiable Threshold Proxy Signature Scheme with Known Signers
In the (t, n) proxy signature scheme, the signature, originally signed by a signer, can be signed by t or more proxy signers out of a proxy group of n members. Recently, an efficie...

On the Security of Some Nonrepudiable Threshold Proxy Signature Schemes
A (t, n) threshold proxy signature scheme enables an original signer to delegate the signature authority to a proxy group of n member such that t or more than t proxy signers can ...
