  1. 1. Avoco Secure<br />The I-Card Cloud Selector<br />CloudCard<br />
  2. 2. An introduction to Avoco’s fully Cloud based I-Card Selector, CloudCard<br />A demonstration of the logon process using the Cloud selector and a shared secret<br />A demonstration of the extended use of Information Cards:<br />Digital signing in the Cloud using Information Cards<br />Access control of documents using Information Cards<br />What you will see today<br />
  3. 3. A fully Cloud based Information Card selector<br />A leap forward in Information Card usability<br />Bypasses the world of Windows desktops<br />Designed to have similar functionality to Windows CardSpace, e.g.<br />Personal cards can be created<br />Cards can be imported<br />Cards can be backed up<br />Works with standard and auditing cards – not yet tested with others e.g. Relationship and Signalling cards<br />Like CardSpace, token encryption is left to IdP for auditing cards<br />CloudCard: What is it?<br />
  4. 4. Usability benefits include:<br />Universal access to your Information Cards<br />True zero footprint for end users – no plug-ins, ActiveX, downloads, etc.<br />Access from normal desktops/laptops as well as phones/mobile devices<br />Test Implementation Site:<br />Why Bother?<br />
  5. 5. Extensibility: Modular design permits simple use of alternative login protocols, etc.<br />Portability: Written in PHP ∴ easy to port to other languages such as Java (if needed)<br />Security: Incorporates anti-phishing technology through shared-secret log in control<br />Security: SSL - MITM attacks less feasible<br />Standards: HTML spec to be submitted as standard <br />Nitty Gritty<br />
  6. 6. CloudCard called as a post from RP web page:<br />&lt;a href=&quot;;RequiredClaims=http....<br />Link specifies entry point to selector, required card issuer, claims, etc., like calling a desktop selector.<br />Additionally certificate of RP is included. <br />RP Use of CloudCard<br />
  7. 7. Used to provide anti-phishing of the I-Card web service account<br />User chooses a photo before logging into their account<br />If correct photo displayed, user can log in knowing the site is genuine<br />A photo always presented to prevent guessing username<br />More on using photos as a shared secret <br />Sir Henry No-Tail<br />
  8. 8. What’s to stop Phisher from Relaying?<br />1. Generate phishing page<br />Phishing server (PS)<br />2. Username submitted<br />CS Backend<br />3. PS submits username to CS backend<br />4. PS gets image from response<br />5. Correct image set in fake password entry page<br />
  9. 9. Session key with real site <br />1. Create page and setup session key<br />CS Backend<br />2. Username submitted<br />with session key data<br />3. Valid Session key: Image returned<br />
  10. 10. Session key with Phishing Site<br />1. Generate phishing page<br />Phishing server (PS)<br />2. Username submitted<br />CS Backend<br />3. PS submits username to CS backend (invalid session key)<br />4. No response<br />5. Cannot set correct image<br />
  11. 11. No protection against desktop Trojan / virus (but then entire system is potentially compromised including desktop selector)<br />Weaknesses<br />
  12. 12. Use your preferred login scheme e.g. OpenID.<br />If you don’t like this...<br />
  13. 13. Face recognition and recognition of familiar objects is part of an acquired evolutionary trait that helps us survive<br />We are good at it<br />We place trust in our ability to use face recognition and object recognition<br />We use processes of cheat recognition all the time, everyday, to interact with others<br />An identity system must mesh real world me with digital me<br />We must use existing human traits when designing the system <br />Human Beings, Digital Identity and Pictures of Familiar Things<br />

  15. 15. The Avoco Cloud Selector is modular, so<br />Can choose to use a myriad of authentication techniques – this presentation shows one<br />Important not to forget the big picture:<br />Usability – for a consumer as well as business audience<br />Represents the real world me in a familiar way<br />I am me because of these reasons (claims)…<br />Can be used not just for logging into web sites<br />Identity is more than just access control<br />Authentication, Authentication or a Bigger Picture<br />
  16. 16. Current Developments<br />Authentication:<br />Digital certificate<br />OpenID<br />LiveID<br />Card authentication specified by RP<br />e.g. only a card backed by X509 can be selected<br />Seamless upload of cards from IdP to Selector – transparent management for users<br />
  17. 17. A system for issuing OpenID’s with an Information Card <br />Links the two ID system – best of both worlds<br />OpenID attributes can be set as a Information Card Claim <br />Information card can be authenticated by that OpenID<br />OpenID linked to the extended claims system of the Information Card<br />Best of each to create a symbiotic ID system<br />Futures: Information cards and OpenID: SymbioticID (SymID)<br />
  18. 18. Requires additional HTML / JavaScript<br />Recommended for web pages to allow user to select a Cloud Selector and Desktop Selector where appropriate / available.<br />How are multiple Selectors to be addressed?<br />Preconfigured to a single Selector<br />Preconfigured dropdown list<br />Dynamic list populated from discovery service.<br />Cloud Selectors: Adoption: <br />
  19. 19. Extending the Uses of Information Cards<br />Digital Signing in the Cloud<br />
  20. 20. Digital certificates are user-unfriendly and unpopular<br />People don’t like to install software, including browser plug-ins<br />Current solutions for signing on-line forms are open to denial of signing caused by only including form text in signature<br />Therefore, to encourage digital signing, these issues must be addressed<br />Why aren’t we all digitally signing?<br />
  21. 21. Avoco Secure have developed first truly Cloud based digital signing<br />Can be used on:<br />On any operating system<br />Using any browser <br />From desktops, laptops, mobile devices, phones and so on<br />Signing does not require user to have X509, but standard PKCS#7 signature produced.<br />Nothing to install – fully Cloud based.<br />Non-repudiation addressed.<br />Signing in the Cloud<br />
  22. 22. Always a problem to identify the signer<br />Avoco – generate repeatable RSA key pair from ID info e.g.<br />Information Card claims<br />OpenID attributes<br />ATM Card numbers<br />Passwords<br />etc., etc.<br />Exact data specified by host<br />Key pair -&gt; transient X509 used to sign with<br />Cert and key pair destroyed after signing<br />Digital Signing and Identity<br />
  23. 23. Image of the completed form incorporated into the digital signature<br />Non-Repudiation of Signature<br />
  24. 24. Incorporates timestamp (RFC3161)<br />Emails signature to user<br />Signature verifiable by common tools as well as Avoco on-line verifier<br />Other<br />

  26. 26. Extending the Uses of Information Card<br />Controlling Access and Applying Usage Policies to Documents and Emails<br />
  27. 27. Controlling access to documents, emails using Identity Information from Information Cards<br />secure2trust<br />secure2email<br />secure2access<br />Claims used to:<br />Control document and email access<br />Apply usage policies, post access<br />Done in a content centric manner<br />Security is persistent across perimeters<br />And there’s more…<br />
