Mobile agents can migrate across different execution environments through the network. One important task of a mobile agent is to act as a proxy signer to sign a digital signature on behalf of the agent owner. As the agent and the remote hosts are not trustworthy, or are probably malicious, there are great challenges for the task. In this paper, we propose an efficient, secure (t,n) threshold proxy signature scheme based on the RSA cryptosystem. The proposed scheme shares the proxy signing key with a simple Lagrange formula. However, it does not reveal any secret information. Owing to its simple algorithm and few parameter requirements, the proposed scheme requires few calculations and few transactions. The proxy signature generation stage and the proxy signature combining stage are completely non-interactive. Furthermore, the size of the partial proxy signing key and that of the partial proxy signature are constant and independent of the number of proxy signers.
