Abstract：In e-commerce, the protection of user’s privacy from a server was not considered fersible until the private information retrival(PIR)problem was stated and solved. A PIR scheme allows a user to retrieve a data item from an online database while hiding the identity of the item from a database server.

In this paper,a new PIR scheme combined with authentication by ElGamal signature algorithm for protecting the privacy of users is proposed. Using only one server (combined with secure coprocessor)and including the mutual authentication process in the proposed scheme, it is more pratical in the rael e-commerce environment compared with previous PIR solutions.
