Homomorphic encryption is a cryptosystem that supports arithmetic operations between ciphertexts. This technology has great potentials in real-world applications since it allows us to securely outsource expensive computation on public (untrusted) server. The security of practical homomorphic encryption schemes...
HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on eff
On-line/off-line encryption schemes enable the fast encryption of a message from a pre-computed coupon. The paradigm was put forward in the case of digital signatures. This work introduces a compact public-key additively homomorphic encryption scheme. The scheme is semantically secure under the de...
The cloud computing is an emerging model in which computing infrastructure resources are provided as a service over the internet. Data owners can outsource
