  2. Secure Devices Manufacturer Operated Services & Solutions 2013-06-20

  3. Web applications & secure devices API signing • Get rid of passwords • Sign Documents Strong Authentication • Electronic Transactions Client side Encryption • Secure Cloud Resources Electronic Signatures • Protect Storage Anonymous Credentials • Safeguard Privacy Digital Money Many use cases… 2013-06-20

  4. The issue: connectivity 2013-06-20

  5. Requirements for a good solution • Number one priority • Simple install & upgrade experience • Ease of use, design clarity, speed, … Usable • New attack vector • Build Trust in solution • End User Consent: Don’t surprise Secure • Adapt to fast moving environment • Don’t break things • Self Update Extensible 2013-06-20

  6. PC SEAM: Architecture PC Server Server Browser Web Application JS Engine Javascript Application Code SEAM Extension SEAM Library Secure Add-Ons Manager Secure Add-Ons Manager Library Add-On (SC) Add-On (BIO) … Add-On (SW) Add-On Library (SC) Add-On Library (BIO) … Add-On Library (SW) Library SW Library SC Library Bio Library Driver SC Driver Bio Driver 2013-06-20

  7. Usability TRANSPARENT SECURITY Minimalistic interactions with end user CLEAR DESIGN Simple, obvious UI with step-by-step install & usage instructions AVOID CLICK GALORE Install & update experience use as few clicks as possible TRANSPARENT UPDATES Updates to Add-ons are transparent and don’t break things SMALLER IS BETTER Initial extension is less than 1 MB, deployed packages as small as possible 2013-06-20

  8. Security • Signed Packages and Extensions • Control Diffusion with Access Keys • Capture user consent at every stage • During install of packages • For each web applications access • Mandate SSL/TLS • Valid certificate, bound to Access Key • Fine grained permissions contained in Access Key 2013-06-20

  9. Extensibility Multiple Hardware Support Multiple Version Support Customizable Easy deployment 2013-06-20

  10. Challenges Many OS / Browsers Combinations… …Walled Gardens… • Heavy deployment constraints • Avoid being seen as malware… • Difficult to maintain a consistent UI • One plugin technology per browsers • ActiveX, XPCOM, NPAPI • One (or more) driver set per OS …And a world evolving fast • One new Chrome and Firefox version every 6 weeks 2013-06-20

  11. What about mobiles? Even more challenges, no perfect solutions • Physical connectivity / drivers are often absent • Closed ecosystem and non extensible browsers • Many more combinations due to Manufacturers and MNOs • Embedded Web Server in Mobile (Gibraltar) • Embedded Web Server in Security Device (over IP enabled physical link) • Extended Hybrid App Framework (Wikipedia) • And of course native applications Alternatives 2013-06-20

  12. Going forward: Standards WebCrypto WG SysApp WG • New security model for hardware access in browsers • More hardware APIs being introduced • “High level” API for cryptography in browsers • Can abstract some security devices 2013-06-20

  13. Thank you! 2013-06-20
