Linda Gricius (March, 1998):
Credentials contain the security attributes of the principal, a "lifetime",
and a few other fields. Credentials are used:
- as a means of making the principal accountable for its actions
- as a means of obtaining access to protected objects
- as a means of identifying the originator of a message.
Security attributes include both authenticated attributes and unauthenticated
attributes.
Authenticated attributes include identity attributes, which identify the principal,
and privilege attributes, which grant rights to the principal.
