Passive Keyless Entry Possible With BLE

Imec demonstrates what it calls the first solution for secure and very accurate passive keyless entry on Bluetooth Low Energy (BLE). This technology enables a seamless car access experience where a BLE device, such as a mobile phone, acts as a digital car key.

 

Imec’s HADM on BLE achieves an accuracy of 30 centimeters, said to be over 10 times better than current approaches, even those already using phase-based ranging techniques. Additionally, it adds a physical layer of security features that create a secure distance measurement between two Bluetooth-enabled communication devices.

With this offering, imec shows that BLE is ready to support a wide new range of disruptive services for proximity applications in a secure and cost-effective way. These range from passive keyless access to cars and smart door-locks to accurate indoor navigation and tire pressure measurement applications. A growing number of cars offer passive keyless entry solutions that automatically unlock a car’s doors as its owner approaches. Yet, ways of electronically stealing a car have become increasingly sophisticated as well – with relay attacking being a well-known risk. For more details, visit imec.
