New security authentication mechanisms in grid computing web environment

The fundamental of the authentication of grid computing web-based environment is to ensure the security of local and remote entities in the environment. The existing authentication mechanisms mostly use public key infrastructure (PKI), but the potential PKI vulnerability and implementation constrains are still cannot be avoid. In order to satisfy the security needs of grid computing web environment, we design new authentication mechanisms, which aim to avoid uploading the public/private key pair to a web portal grid environment through world wide web (www).
