Abstract
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 utilizing expensive pairing operations or vulnerable against a partial decryption attack. In order to address the performance and security is-
sues, 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.
