Client Registration Summary

This document summarizes key open issues regarding the registration universe for entities, focusing on various aspects of proxy registration, authentication, and ownership parameters. It delves into explicit vs. implicit registrations, the roles of certificates and credentials, and ownership questions related to entity management. Furthermore, it explores the requirements for entity objects, including UUIDs and owner definitions, while addressing the complexity of ownership hierarchies and server policies that dictate access and control over cryptographic objects.

  1. Client Registration Summary Update 6/21/2011 Denis Pochuev

  2. List of the open issues • Registration universe • What does the Entity Object look like? • Proxy Registration/Authentication • Open questions regarding ownership

  3. Registration parameters • Explicit vs. Implicit • Certificate and/or Username/Password (and/or other credential types) • Self vs. Other • Pending vs. Synchronous • There are restrictions on the combinations • Implicit can only be Certificate and Self • Pending can only be Explicit • All other combinations are permitted

  4. What does the Entity object look like? • Entity has to contain UUID, Owner, Credential, may contain more Register Object Type=Entity Template-Attribute Attribute Attribute Name: “Credential” Attribute Value: Credential Type: Transport Certificate Credential Value: <empty> Entity UUID: ABCD-1234 <- required Owner: DCBA-4321 <- required (0 = self or actual self UUID?) Attribute <- required (at least one) Attribute Name: “Credential” Attribute Value: … Attribute Attribute Name: “Name” <- not required, really an alias Attribute Value: user1

  5. Proxy Use-cases

  6. Ownership questions • Settled questions: • Does every crypto object have an Entity owner? (Yes) • Does every owner have access to all of its crypto objects and only them? (By default yes, controlled by server policy) • At F2F it was suggested that it should be controlled by profile • Implies that server needs to enforce non-impersonation • Open questions: • Does every Entity have an Entity owner? • Do we allow two levels of ownership hierarchy or infinite? • Does the owning Entity own the Objects of its subordinates (possibly multiple levels)? Does it have access to them? Is it controlled by the policy, profile or else? • Do pre-generated objects from the Group proposal have owners? • Is ownership attribute modifiable by server or by client (Crypto Object or Entity)?
