HMAC authentication mechanisms in a grid computing environment using gridsim toolkit

Abstract

Recently the authentication of grid computing environment has been to secure the security of local and remote entities in the surrounding. The existing authentication mechanisms mostly use public key infrastructure (PKI), but the potential PKI vulnerability and implementation constraints are still cannot be a void. In order to satisfy the security needs of grid computing environment, this paper proposes an authentication mechanism using HMAC (a hash, MAC) to secure the user identification that bears the characteristic of public key replacement attack resistance, which run the experiment in the GridSim toolkit simulator.
