HMI
A secure scalable cloud-managed solution that enables keyless vehicle access via a smartphone.

Digital Key System

Cloud-managed backend
A server providing a set of APIs for pairing a mobile device with a vehicle, authorization, user & vehicle data storage, etc. Includes a push notification service.
Certificate Authority Center
A server for generating, signing, and validating certificates.
Mobile
Using BLE as a communication protocol, the system is smartphone-compatible. Vehicle key management is done via a mobile app.
Hardware configuration
3rd party hardware solution configured and custom software developed that can be seamlessly integrated with all existing in-vehicle modules.

Features

  • - Unlocking/locking the vehicle when the smart device is in/out close proximity
  • - Unlocking/locking the vehicle by user interaction with the smart device
  • - Provisioning the key to another smart device
  • - Revoking the key
  • - Proximity/remote key sharing

Security

Ensuring high-level security
Mechanisms and techniques used for ensuring data and IT security of the Digital Key Solution:
  • Secure QR-codes as means of communicaton between the backend and a mobile device
  • Authorization and authentication mechanisms (including biometrics)
  • A powerful notification engine for vehicle status control
Maximizing BLE security features
Improvements of BLE security model implemented in the Digital Key Solution:
  • 'Read' and 'write' modes feature to provide a smooth auto-locking/unlocking experience
  • Additional layers of encryption (TLS) to provide communications security over BLE protocol
  • Integrity control of a session to protect from man-in-the-middle, replay, and amplified relay attacks

Design

Digital Key solution delivers both mobile and HMI experiences to the user.

HMI UX/UI

HMI interfaces are designed according to the standards (ISO 9241) and the guidelines for in-vehicle display systems.

Mobile UX/UI

Human-centered design approach is applied. High customization and branding capabilities are provided.
