Due to their reconfigurability and their high density of resources, SRAM-based FPGAs are more and more used in embedded systems. For some applications (Pay-TV,Banking, Telecommunication ...), a high level of security is needed. FPGAs are intrinsically sensitive to ionizing effects, such as light stimulation, and attackers can try to exploit faults injected in the downloaded configuration. Previous...
Encryption algorithms could suffer fault injection attacks in order to obtain the secret key. In this paper, a specific protection for any round-based encryption algorithm is presented, analyzed and tested. It is providing a high degree of robustness together with a small penalty in the algorithm throughput when dealing with specific intentional attacks. Experimental results on advanced encryption...
This paper presents an approach to generate secure minutiae information in fingerprint templates. Using triplets of minutia points, useful geometrical properties can be derived from minutia triplets to hide their coordinates, direction of minutia, and scale. This non-invertible transform enables matching from the results in the anonymous domain to fight against malicious attacks to biometrics. The...
