Linearly homomorphic encryption

Nettet20. apr. 2015 · We design a linearly homomorphic encryption scheme whose security relies on the hardness of the decisional Diffie-Hellman problem. Our approach requires some special features of the underlying group. In particular, its order is unknown and it contains a subgroup in which the discrete logarithm problem is tractable. Nettet22. nov. 2024 · Fully-homomorphic encryption (FHE) allows one to evaluate any function over encrypted data. Since the breakthrough result of Gentry [], the development of …

Nettetrate-1 linearly homomorphic encryption from LWE leverages ideas which were originally conceived in the context spooky FHE [13], homomorphic secret shar-ing [3] and private-information retrieval [14]. Concurrent Work. In a concurrent work, Gentry and Halevi [17] constructed rate-1 FHE schemes using similar ideas as in our work. While the goal of ... tally ho 126Homomorphic encryption is a form of encryption with an additional evaluation capability for computing over encrypted data without access to the secret key. The result of such a computation remains encrypted. Homomorphic encryption can be viewed as an extension of public-key cryptography . Homomorphic refers to homomorphism in algebra: the encryption and decryption functions can be thought of as homomorphisms between plaintext and ciphertext spaces. two views of qualityNettetdeveloped a framework called “linearly homomorphic authenticated encryption with public verifiability” (LAEPuV) that allows to combine both primitives into one unified solution.
