Title:
Provable Efficient Certificateless Public Key Encryption
Authors: Yijuan Shi, Jianhua Li
Abstract:Certificateless public key cryptography was introduced to overcome
the key escrow limitation of the identity-based cryptography. It
combines the advantages of the identity-based cryptography and the
traditional PKI. Recently, Dae Hyun Yum1 and Pil Joong Lee have
proposed a generic series construction model of certificateless
public key encryption (CL-PKE) which is built from generic
primitives: identity-based encryption and public key encryption.
However, this model pays much attention on the generic construction
and neglects the nice properties of the bilinear pairings. In this
paper, we propose an efficient CL-PKE scheme which is based on the
nice algebraic properties of Weil pairing. The scheme works in a
kind of parallel model and it is more efficient on computation or
published public key information than the existing schemes.
