NGN and Identity

NGN is the Holly Grail

History of Telecom…was privileged who had access. Until the 60s when people started to see the telephone as a right not a privlidge was not until the late 70s and early 80s and you really had universal access.

Phones were originally used just for voice. What has happened recently – NGN the investment by operators in two networks – IP Network and a telephone network PSTN.

Voice looks like data – no reason to not do voice over a network One network – one networking protocol with lots of services.


  • TDM - PSTN – ISDN same timing base – consistency – 64k bi-direction.
  • IP is asynchronous – no pairing of direction capability - Arbitrary up and down.
  • Mix of psudo-synchronous | and synchronous services.
  • IP is older then TDM and is pre DARPA and became public in 74 and deployed in the 80s. and is being uses in the “NEW Network”

IP based transport for NGN needs to be more ‘secure’ and ‘trustworthy’ ___________

  • E.164 –PSTN - does not tell you much – country code – geographic code – subscriber code. Study group 2 in ITU.
  • ISDN – Integrated Services Digital Network

Alphanumeric forms

  • URI

They tend to be layer specific – Telecom is not a good follower of the 7 layer model Merges layers 4-5-6-7.

No session layer no presentation layer. It didn’t exist before.

______________________ Current state of NGN Identity is currently LAYER specific – Given away and can’t control end point use.

No widely spread user-control capability. Can’t modify use and behavior


Work in UCI (Universal Communications Identifier) space – user shouldn’t have wealth of identities. Single identity and control of services that bind to that identity. Communications correlation a requirement. For privacy it is important to have a plurality.

Two ways to look at it: Strong authentication around a single identity Or multiple identities that might expire.

Privacy – risk of correlation of services Vs. Management of multiple identities and service specific.


Three axis

  • Unification of my fractured identifiers
  • Delegation of the owner of the identifiers and manage services
  • Control – privacy is one of many controls…management framework.


Identity Management has to move towards distributed Convergence vs Control. What are the overall objectives

1) Telecom networks – resolvable to location – needed to connect inbound services 2) Respect privacy – who owns the identity? The one who owns it controls it.


Mark Lizar - Owner ship in law is something that can sold The originator of an identifier – might be thought of as the manager or controller of an identifier Now in internet space is that you buy a domain names. If you own it you play a different role then if you

Scott - In PSTN they are “owned by government” leased to CSP (Communication Service Provider) [europeans are technology agnostic]

  • Identity and its attributes.
  • Security – revocation – E.164 – take out of database.
  • Identity – is distributed set of attributes,
  • Identities and services managed for those identities.

What ever the identity is?

There are different social use of identity. Children use online services they are growing and how they use it changes….

  • Biometrics don’t change but presented personality does change. Must take into account – attributes that we don’t have right now.

User Centric

  • Role Based identities - I would like control of those roles
  • Public Services - Emergency Service..


Identities and Rolls

This sounds like 'anycast'

Paul -

NGN we are talking about things happening in the network
They think it should include it in the terminal.

We think that only the user should be able to corollate identifiers.

I think it is in scope.

IPTV - Accessibility it is a problem in profiling in emergency services.


RESOLUTION SPACE

Where is 'identity'?

Location

  • Geographic
  • Network

Protocols

  • DNS
  • ENUM (putting an E.164 into DNS)
this is not well understood
Infrastructure vs user DNS.
