Creating a secure and efficient device-to-vehicle
communication flow
Choosing the right communication protocols
How can the challenges be
addressed in the R&D stage?

4. Device-to-vehicle communication
models
Back-еnd based communication

Special mobile app
sends a request to the
cloud to open
a vehicle
If cloud authorizes the
access, it sends
a message to a vehicle
to unlock the door

8. Benefits of using both
device-to-vehicle communication
models
design and software studio auto.bambooapps.eu
Guaranteed data transmission in any environments
High level of security of all connections
Sufficient functionality for all use cases
Interoperability and ease of adoption

9. Benefits of using BLE for digital
key solution
design and software studio auto.bambooapps.eu
High level of adoption in cars and smart devices
High data transmission capability and short delay time
High reliability
Low power consumption
Security

10. TLS encryption of all connections
Multiple authorization options (PIN, Face ID, Touch ID)
Additional security features
Additional layers of authorization and encryption

11. User can lock/
unlock the
vehicle
User can view
status of the
vehicle
No BLE signal. User
can see last status of
the vehicle
30m3m
‘Read’ and ‘write’ modes

Additional security features

12. If during data transmission a car or a smartphone doesn’t receive a
response from a counterpart, a session is automatically ended. This
prevents:
replay
amplified replay
man-in-the-middle attacks
