  1. Client Registration Examples Alan Frindell Denis Pochuev 4/26/2011

  2. Certificate Entity: Implicit self-registration • Server implicitly creates Entity record as a side effect of another KMIP request • No special TTLV required – KMIP server extracts needed values from TLS certificate • Client MAY already have a cert signed by a CA trusted by KMIP server • Resulting Object: Entity UUID: ABCD-1234 Credential Credential Type: Transport Certificate Credential Value: Certificate Certificate Type: X.509 Certificate Value: <cert>

  3. Certificate Entity: Explicit self-registration Register Object Type=Entity Template-Attribute Credential Credential Type: Transport Certificate Credential Value: <empty> x-custom1: custom-value1 x-custom2: custom-value2 Entity: <empty> • Certificate fields extracted from TLS

  4. Certificate Entity: Registration Register Object Type=Entity Template-Attribute Credential Credential Type: Transport Certificate Credential Value: Certificate: <certificate> x-custom1: custom-value1 x-custom2: custom-value2 Entity: <empty> • Assumption: Registering Entity has privilege to register Entities

  5. Certificate Entity: Authentication and Access Control Authentication Credential Credential Type: Transport Certificate Credential Value: <empty> • Server looks up Entity based on TLS certificate information • Server policy: may be dynamic mapping or exact match • For access control, server checks authenticated Entity UUID against request object Owner attribute

  6. Username/Password User: Registration Register Object Type=Entity Template-Attribute Credential Credential Type: Username and Password Credential Value: Username: “user1” Password: “password” x-custom1: custom-value1 x-custom2: custom-value2 Entity: <empty>

  7. Username/Password User: Authentication and Access Control • Same as v1.0 Authentication Credential Credential Type: Username and Password Credential Value: Username: “user1” Password: “password” • Server looks up Entity based on Credential (username) • For access control, server checks Entity UUID against request object Owner attribute

  8. Multi-factor Entity: Registration Register Object Type=Entity Template-Attribute Credential Credential Type: Transport Certificate Credential Value: Certificate: <certificate> Credential Credential Type: Username and Password Credential Value: Username: “user1” Password: “password” x-custom1: custom-value1 x-custom2: custom-value2 Entity: <empty>

  9. Multi-factor Entity: Authentication Authentication Credential Credential Type: Transport Certificate Credential Value: <empty> Credential Credential Type: Username and Password Credential Value: Username: “user1” Password: “password” • Server looks up Entity based on each Credential – all must resolve to the same Entity • For access control, server checks Entity UUID against request object Owner attribute

  10. Locate Entity • Find all Entities with Transport Certificate Credentials: Locate Credential Credential Type: Transport Certificate • Find an Entity by its transport certificate: Locate Credential Credential Type: Transport Certificate Credential Value: Certificate: <certificate> • Find yourself: Locate Entity Identifier = Self

  11. Credential Refresh Modify Attribute Attribute: “Credential” Attribute Index: N Attribute Value: Credential Type: Transport Certificate Credential Value: Certificate: <certificate> Modify Attribute Attribute: “Credential” Attribute Index: N Attribute Value: Credential Type: Username and Password Credential Value: Username: “user1” Password: “new-password”

  12. Other operations • Get Entity Info Locate Entity Identifier = Self Get Attributes Attribute Name: “Credential” • Note server is not allowed to return Password values • Destroy Entity Destroy UUID: “ABCD-1234”
