Summary
[edit]DescriptionAttack overview of BrutePrint.png |
English: "We implement BRUTEPRINT system to crack SFA and achieve fingerprint brute-force attack. As shown in Figure 2, there are two kinds of brute-force attackers who exploit CAMF and MAL vulnerabilities. Specifically, BRUTEPRINT acts as a middleman between fingerprint sensor and TEE. Two attacks are firstly implemented to reach ultimate fingerprint brute-force attack. Attempt limit bypassing attack exploits either of the two vulnerabilities to meet R1. Typically, a CAMF exploitation invalidates the checksum of transmitted fingerprint data, and a MAL exploitation infers matching results through side-channel attacks. Fingerprint image hijacking attack meets R2, which has the capability to decode the intercepted fingerprint data and encode replaced data for injection. To increase the success rate of brute-forcing, BRUTEPRINT additionally propose a fingerprint dictionary generation method
that trains a neural style transfer network to transfer available fingerprint database into valid styles." |
