New Recovery Option: External Registration DS

This page contains a preliminary design that implements a new TPS cert/key recovery option in which TPS will obtain key enrollment and recovery information from an external registration Directory Server where user entries are kept. Such an option would allow a site to have control to overwrite the token enrollment, revocation, and recovery policies which were previously inherent to TPS.

  • Base External Registration Design

    • In the first part of this document, it details the Base External Registration Design.

  • Delegation Option

    • In the second part of this document, an optional enhancement called "Delegation Option" is introduced. The Delegation option will be useful in the scenario that a delegate could potentially own a token which contains certain certificates and their keys so that a delegate can act on behalf of the executive.

  • Alternative Base External Registration Design (currently preferred)

    • In the third part of this document, an alternative to the Base Design is introduced. It is to replace the Base Design in how the certs/keys on the token are controlled from the registration database. The introduction of this alternative base design does not affect the delegation option listed above.

Note: Only one of the base designs will be implemented. We currently prefer the Alternative Base External Registration Design and unless we hear otherwise, we will start on the implementation of this alternative base design on 7/15/2013.
