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 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 Base Certification Basic Interoperability
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 Benefit – App Will Work With ML Clients

12 Base Certification Application 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 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 Certification Minimizing 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>www.e-qualus.com</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>0x </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 System ACMS 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
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 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

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 Certificates Testing Application Behavior
ACMS Developer Certificate(s) Dev-Signed Application Certificate Server Device IDs Developer ID, Server Device IDs, Manufacturer Blacklist Status Query Developer IDs, Server Device ID Developer MirrorLink™ Server Device Device ID(s) Input Developer ID(s) Developer ID ML Client Device Manufacturer Name 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 Run Uncertified App In Drive Mode

21 How Do I Certify My Application?
Application Certification Process

22 Application Certification High-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 Overview Key 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 Diagram New Application Certification
Test Lab Performs Tests Developer Decides to Get App Certified Testing Complete? No Developer Makes Changes to App Developer Fills Out PICS & Submit Certification Request Yes Test Lab Issues Report Certification Body Reviews Application No Approve Certification? CB Reviews Report Ready to Test? No Yes Yes ACMS Certificate Issued

25 Engineering Change Orders ECO 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 Lab Performs Tests
Developer Updates App or Certification Testing Complete? Developer Submits Request for New/Updated Certificate on ACMS Portal No Developer Makes Changes to App Yes Test Lab Issues Report No Certification Body Reviews Change Request Approve Change? CB Reviews Report Testing Needed? Yes Yes No ACMS Certificate Updated

27 Member-Certified Applications Alternative 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
