Globus, the most popular toolkit of grid, has been used to develop grid system conveniently. It comprises several security subsystems and MyProxy is an important one of them. As an online credential repository of GSI, MyProxy prevents the users from copying his credentials and private keys between computers. We provide a modified MyProxy by integrating hardware devices into it and construct a system to provide services of key management, crypto operations, etc. By using cryptography and network technologies, the security of the improved MyProxy is enhanced largely.
