Partially homomorphic encryption

Web20 Jul 2024 · Partially Homomorphic Encryption is usable now, but it only supports evaluating one function. The widely used RSA encryption algorithm could be considered an instance of PHE. In its textbook form, RSA allows for the direct multiplication of encrypted numbers, for example: RSA-encrypt (key, 3) * RSA-encrypt (key, 5) = RSA-encrypt (key, 15). ... Web17 Jun 2024 · If there exists an encryption scheme that is partially homomorphic, this means that this scheme is either additively homomorphic or multiplicatively homomorphic. In other words, let’s say that in the Delegated Computation example, we would like the remote server to compute some functionality F .

Web30 Mar 2015 · Shortly, an ' homorphic encryption scheme ' means that you are able to apply operations on the ciphered message and see the result of these operations once the message is deciphered. Usually, these operations are related to arithmetic (which is known to be Turing-complete meaning that you can encode any program in it). Web23 Oct 2024 · 1 If you consider something like "with equal runtime", then almost surely FHE is going to be less secure - usually it's stated the other way around: FHE is really slow compared to semi-homomorphic schemes with similar security parameter. But still, a comparison for that can only benchmark some implementation of the scheme, not the …
