In a multi-tenant scenario, such isolation is paramount to protect tenants from each other and is guaranteed by partitioning resources (memory, peripherals, etc.) between the tenants. Several third-party defence mechanisms ad

A Practical Introduction to Side-Channel Extraction of Deep Neural Network Parametersa device, an adversary may exploit side-channel leakages to extract critical information of a model (i.e., its architecture or internal parameters). Different adversarial objectives are possible including a fidelity-based scenario where the architecture and parameters are precisely extracted (.). We

Guarding the First Order: The Rise of AES Maskingsster stages. All maskings use a generalization of the changing of the guards method enabling the re-use of randomness between masked S-boxes. As a result, the maskings do not require fresh randomness while still allowing for a minimal number of shares and providing provable security in the glitch-ex

Rivain-Prouff on Steroids: Faster and Stronger Masking of the AESattacks. RP masking is provable secure in the probing model, but this solid theoretical underpinning comes at the cost of a massive increase in execution time. In this paper, we describe software optimization methods to accelerate the low-level arithmetic in the field ., which has a significant impa
