摘要:In a (t, n) threshold proxy signature scheme, the original signer can delegate his power of signature to n proxy signers in a proxy group, and only at least t proxy signers can sign any message on behalf of the original signer; One-time proxy signature is that the proxy signer only signs message for the original signer at most one time. These two kinds of signatures both control the power of the proxy signer efficiently. In this paper, combining the two kinds of signature, we get a new threshold one-time proxy signature scheme. Different with the previous threshold one-time proxy signature schemes, our system needn't be reset after finishing the proxy signature each time, that is to say, the signature keys and the verification keys can be used more times which greatly improve the efficiency of the proxy schemes. © 2010 IEEE.
