Abstract
The most prevalent grid security standard, grid security infrastructure uses an authentication protocol based on public key infrastructure (PKI). Certificateless public key cryptography (CL-PKC) overcomes PKI certificate management problems and is well aligned with grid computing demands. Security and efficiency are the main grid authentication protocol objectives. Practical, efficient CL-PKC-based authentication protocols for real grid environments is widely acknowledged as a challenging issue. Unfortunately, certificateless authenticated key agreement protocols rely on bilinear pairings, which are extremely computational expensive. In this paper, we present a novel pairing-free certificateless two-party authenticated grid key agreement (GPC-AKA) protocol, providing a lighter weight key management approach for grid users. We then propose the first practical GPC-AKA implementation as a proof of concept. We also compare the efficiency of GPC-AKA to other proposed work in the literature.
