WebSep 1, 2024 · Homomorphic encryption (HE) is a promising privacy-preserving technique for cross-silo federated learning (FL), where organizations perform collaborative model … WebInspired by recent side-channel attacks, especially the "cold boot attacks", Akavia, Goldwasser and Vaikuntanathan (TCC '09) formalized a realistic framework for modeling the security of encryption schemes against a wide your of side-channel attacks included which adversarially chosen feature of the secret key are leaked.
WebIn this paper we introduce an abstraction of this problem which we call "homomorphic sensing". Given a linear subspace and a finite set of linear transformations we develop an algebraic theory which establishes conditions guaranteeing that points in the subspace are uniquely determined from their homomorphic image under some transformation in the set. WebOct 29, 2024 · Encryption schemes often derive their power from the properties of the underlying algebra on the symbols used. Inspired by group theoretic tools, we use the centralizer of a subgroup of operations to present a private-key quantum homomorphic encryption scheme that enables a broad class of quantum computation on encrypted data.
