Abstract
In a cryptographic device (140) storing a number of templates (310), a system and method for supporting authentication services is provided. The cryptographic device (140) receives inputs representing a request for authentication services. The cryptographic device (140) then compares the syntax of the input to the syntactic constraints defined in one of the templates (310), where each template (310) includes syntactic constraints associated with at least one authority. When the cryptographic device (140) determines that the syntax of the input is consistent with the template (310), the cryptographic device (140) validates the input.
