This paper constructs two systems of attribute-based encryption without presenting user's global ID. In our first system, a trusted central authority assists each attribute authority to independently run a security check for users' requests. In our second system, discrete Fourier transform and inverse discrete Fourier transform are used to share and recover secret key, respectively. Finally, proposed scheme not only improves user's privacy while defending against collusion attack but also is more efficient than existing schemes.
