Abstract: Based on Shao et al’s ID-based proxy re-signature, an ID-based bidirectional threshold proxy re-signature scheme in the standard model is presented in this paper. Our scheme eliminates the cost of restoring and managing certificates, and solves the difficult problem of excessive rights of the proxy in the proxy re-signature shceme. The scheme can tolerate t
