Certificateless Public Key Encryption with Equality Test

Xi-Jun Lin, Zhen Yan, Qi Zhang and Haipeng Qu

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.
