Context:
Acoustic Side Channel Attacks are increasing – use of AI deep learning can now be used to crack passwords by analysing keyboard strokes
About Side Channel Attacks (SCAs)
- SCAs are a method of hacking a cryptographic algorithm based on the analysis of auxiliary systems used in the encryption method.
- These can be performed using a collection of signals emitted by devices, including electromagnetic waves, power consumption, mobile sensors as well as sound from keyboards and printers to target devices.
- Once collected, these signals are used to interpret signals that can be then used to compromise the security of a device.
About Acoustic Side Channel Attacks (ASCA)
- In an ASCA, the sound of clicks generated by a keyboard is used to analyse keystrokes and interpret what is being typed to leak sensitive information.
- ASCA attacks are not new and have been around since 1950
- AI models are now used to do ASCA with around 95% accuracy.
- These attacks are particularly dangerous as the acoustic sounds from a keyboard are not only readily available but also because their misuse is underestimated by users.
- While there is no explicit means of defence against ASCAs, simple changes to typing could reduce the chances of attacks.
