....public keys. When an application receives a request to execute a particular action, then authentication notwithstanding, the application uses credentials provided by the requester to determine whether or not the request is authorized. Trust Management approaches such as KeyNote [3] and SPKI [4] provide assistance to applications in making these decisions.

If the principal is authorized then it is safe to write and sign a new single credential. This certificate reduction [4] can be used to reduce the size of delegation chains and may also provide for a degree of anonymity [1] long delegation chains may reveal sensitive information about how authority was acquired. For example, if Steve reduces the certificate chain to Angela s authority (Example 1) by issuing a ....
