Abstract

In this paper, we propose the concept of certificateless public key encryption with equality test (CL-PKEET) to solve the key escrow problem in IBEET. More in details, we first give the definition of CL-PKEET and define the security model. Finally, we propose a concrete CL-PKEET scheme based on the Decision Bilinear Diffie-Hellman (DBDH) assumption and prove its security.

Note: There is a mistake need to be modified in this paper.
