International audienceHomomorphic encryption (HE) ensures provable secrecy of data processed in the ciphertext domain. However, it happens that FHE private-key algorithms can be broken by side-channel attacks. We disclose a novel cache-timing attack on the SEAL open-source HE library. It is triggered by a non-constant time Barrett modular multiplication, which is one of the building blocks in SEAL. We both analyze the mathematical conditions upon which the leakage occurs and show the experimental feasibility of the attack
