We propose a mediated certificateless encryption scheme without pairing operations. Mediated certificateless public key encryption (mCL-PKE) solves the key escrow problem in identity based encryption and certificate revocation problem in public key cryptography. However, existing mCL-PKE schemes are either inefficient because of the use of expensive pairing operations or vulnerable against partial decryption attacks. In order to address the performance and security issues, in this poster, we propose a novel mCL-PKE scheme. We implement our mCL-PKE scheme and a recent scheme, and evaluate the security and performance. Our results show that our algorithms are efficient and practical.
