James Posted June 14, 2022 Report Share Posted June 14, 2022 Microsoft SEAL is an open-source homomorphic encryption library that enables running computations directly on encrypted data. A cloud provider does not have unencrypted access to the data they are storing and computing on. SEAL comes with two homomorphic encryption schemes. BFV allows modular arithmetic on encrypted integers. CKKS allows additions and multiplications on encrypted real or complex numbers, but yields only approximate results. https://www.microsoft.com/en-us/research/project/microsoft-seal/ Quote Link to comment Share on other sites More sharing options...
James Posted June 14, 2022 Author Report Share Posted June 14, 2022 Microsoft SEAL prior to v3.6 using the Brakerski/Fan-Vercauteren (BFV) protocol is vulnerable to a power-based side-channel attack. Aydin Aysu at North Carolina State University demonstrated that by monitoring power consumption in a device that is encoding data for homomorphic encryption, you can read the data as it is being encrypted. https://securityboulevard.com/2022/06/researchers-demonstrate-they-can-steal-data-during-homomorphic-encryption/ Quote Link to comment Share on other sites More sharing options...
