A novel ID-based proxy-protected signature scheme based on identity information is presented in this paper. We review the concept ID-Based signature introduced by Shamir, define the security notion of an ID-Based signature. We also improve the Shaimr's ID-Based signature and prove its security under the proposed security notion. From the improved Shamir's ID-Based signature scheme we construct an ID-Based proxy signature scheme, the security is based on the underlying ID-based signature scheme. Our scheme is efficient and easy to implement. The scheme simplifies the public key as the user's id and can be easily applied to all the RSA-type cryptosystems. © Springer-Verlag Berlin Heidelberg 2005.
