Abstract

This paper relies on the traditional method RSA-OAEP with an identification-based encryption. Firstly, we make a little change in the basic idea Boneh et al., 2002; Ding and Tsudik, 2003 in order to create a scheme with which we can sign and crypt at same time. A simple comparison prove that our signature is equivalent to the signature of Shamir. Then, we propose a new approach, which conserve properly the RSA classic. In this paper we will also respond to the question of Xuhua Ding and Gene Tsudik, to propose a convenient exponent for an RSA-IBE.
