6 Identity - Problems Passwords Too easy to crack, or too hard to remember I want multiple identities Because I don t trust all recipients the same Results in identity silos on the web Banks etc. would like sign-on to be much more complex Human beings are the limiting factor Nobody trusts a single organization...

7 Identity What s the problem?

8 Identity What s the problem?

9 Identity - Solutions Must work cross-platform Must allow me several identities Must put me in control of my identities Must not put a single org. in charge Must allow recipients to define arbitrarily complex sign-on data...and protect the user from that complexity

10 What have we got? WS-* specs give us cross-platform comms SAML tokens are a standard way to exchange identity claims Putting these together inside an open, consistent architecture gives us... The Identity Metasystem

11 The Identity MetaSystem Relying Party 2. I would like a SAML 1.1 token, containing First Name, Surname, issued by *any* 3. UI filters cards that can satisfy policy Policy 1. Access resource 4. User picks a card 7. Token is presented 6. Token is created 5. Token is requested Identity Provider

12 Types of Information Card Personal Card Refers to self-issued security token Securely stored on user s PC Fixed set of claims available Managed Card Refers to Identity Provider that can issue tokens User s PC stores only the IP details Claims are extensible

13 Windows CardSpace

14 What s in the HTML? <form id="form1" method="post" action="login1.aspx"> <div> <button type="submit">click here to sign in</button> <object type="application/x-informationcard" name="xmltoken"> <param name="tokentype" value="urn:oasis:names:tc:saml:1.0:assertion"/> <param name="issuer" value=" <param name="requiredclaims" value=" nalidentifier" /> </object> </div> </form>

15 Communications ASMX Basic, Open Comms Ent Services Secure, Transactional WSE Secure, Open Comms Remoting Fast, Secure, Binary Sys.Messaging MSMQ, Txns, Queuing

16 Distributed Applications Client Message (SOAP) Message Headers: Addressing, Security, etc. Service Body: Payload Message Metadata Services pass messages described by a contract Service may provide metadata, describing: - The contract The policy applied to communication

17 Mechanics of Communication Client What Contract do I send? Service Where Address do I send it? How should Binding I send it? Security? Encoding? Transport?

18 Mechanics of Communication Client Service Endpoint Endpoint Address Binding Contract Address Binding Contract Endpoint Address Binding Contract

19 Basic WCF

20 Metadata WCF sketched architecture Client Service Your code objects XML Your code behaviours formatting Binding (ordered list of channel types & config) behaviours channel channel type 1 config channel channel channel type 2 config channel channel channel type N config channel encoding Transport Channel (HTTP, TCP, MSMQ, Pipes, Peer) decoding

21 Instancing, Concurrency, Sessions Service classes can be instantiated: - Singleton, Per-Call, Per-Session, Shareable Service code can be either: - Single threaded, Re-entrant or Multi-threaded Service Message A Message B Singleton Client Message C

22 Instancing, Concurrency, Sessions Service classes can be instantiated: - Singleton, Per-Call, Per-Session, Shareable Service code can be either: - Single threaded, Re-entrant or Multi-threaded Service Message A Single Call Message B Client Message C Single Call Single Call

23 Instancing, Concurrency, Sessions Service classes can be instantiated: - Singleton, Per-Call, Per-Session, Shareable Service code can be either: - Single threaded, Re-entrant or Multi-threaded session Client Message A Message B Message C Service Per Session Per Session
