This year, we mainly had two achievements.
First, we have constructed an experimental environment for the remote side-channel attack. We used the same attack target from the previous work named BLEnano. We are able to remotely observe and collect the radio signal, which is used for Bluetooth communication and contains side-channel leakage. Also, we successfully recovered the secret key using the collected radio signal.
Second, we noticed the difference between Bluetooth-based signal and near-field electromagnetic radiation in their leakage models and proposed a new key recovery method to combine these two types of information leakage. The new method can reduce the number of accessing the attack target. The relevant result was published at SCIS 2022.
