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 …
