The threshold proxy signature scheme allows the original signer to delegate a signature authority to the proxy group to cooperatively sign message on behalf of an original signer. In this paper, we propose a new scheme which includes the features and benefits of the RSA scheme. Also, we will evaluate the security of undeniable threshold proxy signature scheme with known signers. We find that th...

In a (t, n) designated verifier threshold proxy signature scheme, an original signer can delegate his/her signing power to n proxy signers such that any t or more out of n proxy signers can sign messages on behalf of the original signer but t− 1 or less of the proxy signers cannot generate a valid proxy signature. Of course, the signature is issued for a designated receiver and therefore only t...
