Key points
- Lack of effective authentication has resulted in numerous security and privacy breaches, including unauthorized access to protected information, identity theft, and fraud.
- Some secondary authentication factors include SMS text verification codes, biometrics, and tokens.
- By measuring the behavior of the Dynamic Voltage and Frequency Scaling (DVFS) governor remotely from within a browser, unique properties of the CPU can be leveraged to establish a hardware-based device fingerprint for use in CPU-Auth.
- The performance of CPU-Auth is evaluated on over 50,000 data traces using distance-based and deep learning methods.
