The predominant grid authentication mechanisms use public key infrastructure (PKI).Nonetheless, certificate-less public key cryptography (CL-PKC) has several advantages that seem to well align with the demands of grid computing.Security and efficiency are the main objectives of grid authentication protocols.Unfortunately, certificate-less authenticated key agreement protocols rely on the bilinear pairing, that is extremely computational expensive.In this paper, we analyze the recently secure certificateless key agreement protocols without pairing.We then propose a novel grid pairing-free certificate-less two-party authenticated key agreement (GPC-AKA) protocol, providing a more lightweight key management approach for grid users.We also show, a GPC-AKA security protocol proof using formal automated security analysis Sycther tool.
