Latest Patents

One of her latest patents is a method for securing an AES block cipher algorithm against high-order side-channel attacks. This method involves performing a substep of field inversion by a cryptographic device. It includes computing a Dirac output value, adding it to one of the shares of the first set of shares to obtain a second set, and converting this second set from additive to multiplicative sharing. The process continues with the inversion of each share and further conversions to ensure robust security against potential attacks.

Another notable patent is a method for securing a multiple point multiplication operation against side-channel attacks. This method is part of an elliptic curve cryptographic process that utilizes predetermined scalar values. It involves generating a masking value, multiplicatively masking each scalar value, and computing a masked multiple points multiplication operation result. The final result is obtained by unmasking the masked operation result, ensuring the integrity of the cryptographic process.
