WL18XX-BT-SP: WL1831-BT-SP

Part Number: WL18XX-BT-SP
Other Parts Discussed in Thread: WL1831

Tool/software:

Hi,

I am Suhel Mulla. I am part of the firmware team in Philips Healthcare Innovation Centre at Pune, India. 

This query is related to the Bluetooth KNOB attack on the WL1831. As per observation, the encryption key length can be reduced by key negotiation to minimum of 7bytes.

To avoid low key length, I am looking a way to enforce the key length to 16bytes.

Could you suggest possible ways to achieve this?

Regards,

Suhel Mulla
