Provable Data Possession using Additive Homomorphic Encryption
Journal of King Saud University: Computer and Information Sciences, 2022 Efficiency, public verification, and robustness are essential characteristics of data possession schemes. The efficiency of such kinds of Provable Data Possession (PDP) schemes is possible due to homomorphic encryption, which is used to verify the ...

An overview of torus fully homomorphic encryption [PDF]
International Journal of Group Theory, 2023 The homomorphic encryption allows us to operate on encrypted data, making any action less vulnerable to hacking. The implementation of a fully homomorphic cryptosystem has long been impracticable. A breakthrough was achieved only in 2009 thanks to Gentry

Experimental quantum homomorphic encryption [PDF]
npj Quantum Information, 2021 AbstractQuantum computers promise not only to outperform classical machines for certain important tasks, but also to preserve privacy of computation. For example, the blind quantum computing protocol enables secure delegated quantum computation, where a client can protect the privacy of their data and algorithms from a quantum server assigned to run ...

Verifiable Rotation of Homomorphic Encryptions [PDF]
, 2009 Similar to verifiable shuffling (mixing), we consider the problem of verifiable rotating a given list of homomorphic encryptions. The offset by which the list is rotated (cyclic shift) should remain hidden. Basically, we will present zero-knowledge proofs of knowledge of a rotation offset and re-encryption exponents, which define how the input list is ...
