  4. What is Certification?High-Level Overview of Application Certification • Risk Reduction – Reduce Risk that Application Doesn’t Work • CCC Publishes Requirements for Applications • Base Certification – Does it work in MirrorLink session? • Regional Drive Certification – Does it (not) distract the driver? • Testing Performed by CCC Approved Test Labs • Does the application comply with the CCC’s requirements? • CCC Approves Applications for Use in MirrorLink • Certified Applications Can Use MirrorLink Logo & Certification Mark in their Application & in their App’s Promotional Material Goal: Create Ecosystem of Trusted Apps

  5. How Do I Make a MirrorLink App? MirrorLink Common API

  6. Making MirrorLink AppsHow do I make my app work with MirrorLink? • Become MirrorLink Aware • Provide application metadata via self-signed certificate • Remote framebuffer, scaling, audio streaming and control mapping transparent to application • Use the MirrorLink Common API • Update application metadata • Discover capabilities of MirrorLink Client • Respond to status messages from MirrorLink Client • Virtual keyboard and controls • Take advantage of data services Application MirrorLink Server (Phone) MirrorLink Server (Phone) MirrorLink Server (Phone) MirrorLink Common API MirrorLink Client (Head Unit) MirrorLink Client (Head Unit) MirrorLink Client (Head Unit)

  7. MirrorLink Common APIStandard MirrorLink Server Application Interface • Each Platform has Platform-Specific ML Common API Definition • Android Common API defined • Other platforms pending • Each Server Device Maker is Responsible for Implementing the ML Common API • Device Certification Tests for Common API Functionality and Compliance • Common API test cases • Common API test application MirrorLink Does Not Create Compatibility Problems

  8. MirrorLink Common APIExample Common API Definition • Event Configuration Information • Obtain information about the events supported by the MirrorLink Session • Event Configuration Callback • Notification to application if the Event Configuration Information has changed

  9. Why Certify My Application? Base and Regional Drive Certifications

  10. Types of Certification & Benefits • No Certification – No Guarantee of Availability in MirrorLink Session • ML Server (phone) may not advertise application to the ML Client • ML Client (head unit) may not present application to User • Base Certification – Guaranteed Availability While Not Driving • ML Server required to advertise the application to the ML Client • ML Client required to list application to user while not driving • Drive Certification – Guaranteed Availability While Driving (Per Region) • ML Server required to advertise the application to the ML Client • ML Client required to present application to user while driving • Certified Applications Listed and Promoted by CCC • Use MirrorLink logo & certification mark in application promotional materials

  11. Display Compatibility Support Reference Client Display 800 x 480 pixels (square) 13.33 cm x 8.00 cm 90 cm from driver Adapt to Client Display [Optional] Support Landscape Mode Control Positioning Not entirely within outer 5% of the display Control Compatibility Support Rotary Knobs May not have a rotary keyboard available, so either implement your own, or don’t require Support Single-Touch Events Cannot require multi-touch Voice Commands May use, but may not be available Must notify user if not available Cannot Require OS Keys May not be present on Client Provide Application Metadata Base CertificationBasic Interoperability Benefit – App Will Work With ML Clients

  12. Base CertificationApplication Metadata • Provide Information to the ML Client About the Application • Application type • Framebuffer context information – visual content categories • Audio stream context information – audio content categories • ML Client Uses Information To Determine What Has Priority • Application Types • Long list of types • Can be provided on a per-screen area basis • Visual Content Categories • Text, Video, Image, Vector Graphics, 3D Graphics, User Interface (e.g. Application menu), Miscellaneous Content • Can be provided on a per-screen area basis • Audio Content Categories • Phone Audio, Media Audio Out, Media Audio In, Voice Command Out, Voice Command In, Miscellaneous Content App Category Navigation Visual Content Category Vector Graphics App Category – General UI Framework Visual Content Category – Vector Graphics

  13. Drive CertificationMinimizing Driver Distraction • Guiding Principals • Nothing that demands the driver’s attention • Quickly comprehendible and accessible • Restricted Content • No video, incidental animations or flashing • No automatic scrolling text • Visual Accessibility • Color contrast – brightness & color differences • Text legibility • Minimum height • Font requirements • Control Accessibility • No two-handed operations • Should not use the keyboard • Control sizing and spacing • Pace of Interaction • Input retention and responsiveness • Notification dismissal • Region-Based Certification • Region Specific • North America • European Union • APAC • Global Certification • Superset of NA, EU and APAC guidelines • Pending • Can Get Certified for One or Multiple Regions • E.g. Drive in EU & APAC, but not NA

  14. How Do I Certify My Application? Application Certificates and the ACMS

  15. MirrorLink Application Certificates <appIdentifier>ACMSDemo1234abcd</appIdentifier> <appListEntry> <name>ACMS Demo 1</name> <providerName>E-Qualus</providerName> <providerURL></providerURL> <description>A demo app.</description> <iconList> <icon> <mimetype>image/png</mimetype> <width>72</width> <height>72</height> <depth>24</depth> <url>/resources/icon.png</url> </icon> </iconList> <appInfo> <appCategory>0x00080000</appCategory> </appInfo> . . . • X590v3 Certificate • Signed by the the CCC’s Root Certificate Authority • Contains MirrorLink XML Extension • MirrorLink XML Extension • Descriptive information about the application • Information on how to list application on MirrorLink Client • Content categories • Base certification regions • Drive certification regions • Generated & Distributed by the CCC

  16. Application Certificate Management SystemACMS for App Developers App Certificate Management System Car Connectivity Consortium Device Makers Management Portal Certificate Distribution Certification Body Test Labs Application Certificates distributed to server devices over the Internet. Developers App & Dev Certificates Apps MirrorLink®Server Devices Phones & other mobile devices App Stores Apps do not contain Application Certificates. Apps ACMS Integration Requires No Changes to Application MirrorLink® Client Devices Head units App Certificate tells Servers & Clients when the app is safe to use, and where.

  17. Application Life Cycle • Standard Application • No MirrorLink functionality • MirrorLink Aware Application • Indicates to Server that app MAY have a certificate provided by the ACMS • Indicated to Server in platform-specific fashion • Android – Include self-signed certificate in APK, bind to MirrorLink API intents • MirrorLink Server will check with the ACMS for an application certificate • MirrorLink Certified • Certificate available from the ACMS Standard Application MirrorLink Aware Application May have a Certificate on the ACMS Platform-specific indication. • MirrorLink Certified Application • Certificate provided by the ACMS MirrorLink Aware Apps Can Become Certified At Any Time

  18. Application Certificate Updates Application Perspective Can Distribute Application Prior to Certification When certification is granted, MirrorLink Servers will automatically download application certificate when it becomes available Changes to Certification Status Do Not Require Changes to Application • Certificate is updated and distributed to devices in the field • MirrorLink Servers Periodically Check With ACMS • Checks for to see if any application certificates have been updated • Check frequency controlled by ACMS • ~7 days, initial rate • Certificate Update Process • Revoke existing certificate • Issue a new certificate • MirrorLink Server downloads new certificate from ACMS

  19. Application ID & Security • Identifies an App to the ACMS • “Do you have a certificate for an app with this App ID?” • How the App ID is Generated is Platform Specific • In general, a hash of the application files • Android – Hash of the contents of the Android Manifest • Anytime the Application is Updated, the App ID Changes • Updates to the application cause the App ID to change • MirrorLink Server Checks That the App ID in the Certificate Matches the App ID of the Application Ensures That Running App is the Application that Was Certified

  20. Developer Requests a Developer Certificate via ACMS Portal Provides IMEI to ACMS SMP Provides IDs of Server devices ACMS generates Developer ID Developer Inputs Developer ID into MirrorLink Server Device Server device requests developer certificate from ACMS Developer Provides MirrorLink XML Extension in Application Self-signed certificate (typical) MirrorLink Server Presents MirrorLink XML Extension Provided By Developer As CCC-Signed Developer CertificatesTesting Application Behavior ACMS Developer Certificate(s) Status Query Developer ID, Server Device IDs, Manufacturer Blacklist Developer IDs, Server Device ID MLClient Device MirrorLink™ Server Device Device ID(s) Manufacturer Name Dev-Signed Application Certificate Server Device IDs Input Developer ID(s) Developer Developer ID Run Uncertified App In Drive Mode

  21. How Do I Certify My Application? Application Certification Process

  22. Application CertificationHigh-Level Overview (Redux) • CCC Approves Applications for Use in MirrorLink • Base Certification – Does it work? • Drive Certification – Does it distract the driver? • Testing Performed by CCC Approved Test Labs • Does the application comply with the relevant requirements? • MirrorLink Servers (Phones) Provided Certification Status Information for Installed, Certified Applications • Applies for specific version of the app on a given server platform • Certified Applications Can Use MirrorLink Logo & Certification Mark in their Application and in their Applications Promotional Material Goal – Create Ecosystem of Trusted Apps

  23. Certification Process OverviewKey Elements • CCC Authorized Application Test Lab (ATL) • Approved by the CCC to perform testing • Demonstrated capability to perform needed testing • Periodically audited by CCC lab manager • List maintained by CCC • Application developer arranges testing directly with the ATL • Application Certification Body • Assesses application and test reports • Approves/rejects apps for certification based on requirements & testing results • Assesses requests to change application certification status • Examines changes to application and application certification requirements • May call for additional testing or re-testing on a case-by-case basis • Protocol Implementation Conformance Statement (PICS) • Statement of what the application does • Used to determine what tests to run

  24. Certification Process DiagramNew Application Certification Test LabPerforms Tests Developer Decides to Get App Certified Testing Complete? No Developer Makes Changes to App Developer Fills Out PICS & Submit Certification Request Yes Test LabIssues Report Certification Body Reviews Application No Approve Certification? CB Reviews Report Ready to Test? Yes No Yes ACMS Certificate Issued

  25. Engineering Change OrdersECO Process • Applications Change All the Time • Certification status needs to be changed • Application ID changed, so a new certificate is needed • Don’t Want to Retest the Application Every Time There is an Update • Instead, We Use an ECO Process • Inform CCC of the change to the app • App CB determines if re-testing is needed ECO Process Reduces Testing Burden, & Allows For Updating of Applications

  26. ECO Process Flow Test LabPerforms Tests Developer Updates App or Certification Testing Complete? No Developer Submits Request for New/Updated Certificate on ACMS Portal Developer Makes Changes to App Yes Test LabIssues Report No Certification Body Reviews Change Request Approve Change? CB Reviews Report Testing Needed? Yes Yes No ACMS Certificate Updated

  27. Member-Certified ApplicationsAlternative Certification for Applications • CCC Member Companies Can Certify Applications • Application will be considered certified on MirrorLink Clients from that Member Company • Not required to be available on Clients from other Member Companies, and probably will not be available • Uses ACMS-Distributed Certificates • Certifying entity is listed as Member Company, rather than CCC • Multiple Member-Certifications Possible • Can have multiple certifying entities listed, including CCC and member companies • Allows for member companies to “extend” application operation for their Clients – e.g. add drive-mode operation • Member certification can be tailored to specific vehicle models (vendor specific) • Member Company Controls Parameters of Member-Certification • Blacklisting Possible, But Only Under Exceptional Circumstances
