Design of unified key management model using XKMS

In this paper, we design key management protocols and services with unified single interface, which extend the scheme and services of XKMS, for various kinds of security information such as, private key, secret key, biometric information, security tokens for Web service, and the like. The model we propose modifies and extends the protocols and services such as key registration, reissue, revocation, recovery, location service and validation for only public key pair to provide a way to manage other security information including public key pair. We also describe the processes and structures of the model comparing to legacy them of XKMS model
