  1. USB Flash Drives: Protecting Data And Enhancing Storage Steffen HellmoldVP and General ManagerUFD BULexar

  2. Presentation Outline • History of UFD standardization • User’s security value metrics • Advantages of standard security solutions • Evolution of the UFD – a vision • USB Lockable Storage Device specification • Compelling technology design considerations • Future Lexar technologies • Demo • Call to action • Additional resources

  3. History Of Lexar’s UFD Standardization Efforts • At WinHEC 2003 four aspects of USB flash drives requiring additional standardizationwere identified • New category name for USB Flash Drive (UFD) • UFDA founded end of 2003, initially focused on establishing category name and educate consumers about UFDs • Physical Form Factor for USB Flash Drive • USB-IF approved the Series ‘A’ Plugform factor Guideline 1.0 – 2005 • Bootability support for USB Flash Drives • Windows Vista “Core System” logo certificationrequirement (Consumer and Business SKUs) • Security for USB Flash Drives

  4. User’s Security Value Metrics Easy to Use Low Cost Highly Secure Solution

  5. Advantages Of Standard Security Solutions • No need to exploit“Windows XP backdoors”and use spoofing to launchpassword systems software • Seamless integrationinto Windows • Avoiding legacy issues • Don’t need to use Vendorunique commands limitingthe solutions to specific hardware One UFD

  6. Evolution Of The UFD – A Vision • Past • In the beginning, USB Flash Drives (UFDs) enabledtheir users to take their data with them everywhere • Present • Then, USB Flash Drive manufactures created small, stand-alone, proprietary applicationswhich could be run from the UFDs • Today, Portable Working Environments enable us to installand run a wide variety of programs from our UFDs • Future • My data → my data and apps → my data and apps and OS

  8. USB Lockable Storage • Purpose • USB-IF Implementers Forum international standard-royalty free • Extend USB Mass Storage Classto allow hosts and devices to lockand unlock storage, without breakinglegacy behaviors that exists today • Key Scenarios • Protect for loss/theft • Ensure privacy of data

  9. What Is USB Lockable Storage? Legacy / Impersonal Mode

  10. USB Locking User Experience Plug-in Successful Passphrase

  11. USB Lockable Storage Feature Negotiation • Feature negotiation • No impact on legacy systems • Lockable Storage InterfaceExtension Descriptor (LSIED) • USB parser already knows how to handle Extension Descriptors from HID devices • Allows future features to be added

  12. USB Lockable Storage Command Set • Nine new USB commands specified • Store, match, and change Passphrase • Erase Passphrase (return to Impersonal) • Electronic unplug • Originally used to update firmware • Now we change PIDs to unlock

  13. Compelling Technology Design Considerations • Personal storage device environment • Integrating support intothe Windows Storage Stack • PC OEM and Enterprise concerns • Value add opportunities • Reusable architecture

  14. The Personal Storage Device Environment Legacy OS 1 2 1998 – 2005 Legacy“MSC Device” 2006 – 20xx New“Personal Storage Device” 4 3 New OS

  15. Window’s USB Stack Changes • A new Device Class • Requires additional driverfor locked devices • Launches Windows “Found New Hardware” experience if locked and no driver • When device is unlocked we switchback to USBSTOR.SYS • USBSTOR.SYS • Standard Windows driverfor USB mass storage

  16. Lexar’s PSD-Lock™ User Locked Device driver USBSTOR.SYS USB.SYS Window’s USB Stack Changes Application Application Provided by Microsoft User User ISV Vendor Unique USBSTOR.SYS Lexar IHV USB.SYS USB.SYS Std. Device Hardware Device Windows Inbox

  17. Technology Benefits • Open architecture • High percentage of end-userlost/theft scenarios addressed • No additional system/device overhead • Enables features for all markets • Consumer level locking withoutadditional cost • Extensible architecture for morecomplex locking policies • No licensing fees

  18. Added Value Opportunities Built-in Windows Shell support Continued standards activity Easy to Use USBLockableStorage Highly Secure Low Cost PC Industry adoption Continued standards activity Built-in Windows driver support Password strength protectionmechanisms Biometrics Add HW Encryption Integrate into CentrallyManaged software Harden saved passwords in Windows Continued standards activity
