Comparison SchemesHomomorphic EncryptionComparing two integers under the encrypted form is useful for privacy-preserving data mining, secure auction, and so on. Based on the ring-learning with errors (ring-LWE)
Algorithm 3: Hu's comparison protocol At DO A:Generates a homomorphic encryption key pair (pk, sk);Gets the binary of x as x = xkxk − 1…x1;Encrypts each bit of x separately, ci = Epk(xi), 1 ≤ i ≤ k;Sends the ciphertexts and pk to DO B;At DO B:Encrypts 1 and −...
Homomorphic encryption is considered a major privacy-preserving technique, especially in, but not limited to, machine learning (Aono et al.2017). Even though the need for privacy-preserving techniques has been stressed by many in the context of ABAC (i.e., Xu et al. (2020); Park and Chun...
We demonstrate the use of such a scheme with a simple and efficient “opinion poll” protocol, secure against active adversaries, which would not be possible using existing notions of homomorphic encryptions (unless used in conjunction with tools like zero-knowledge proofs). We also study the ...
Last month, IBM made some pretty brash claims about homomorphic encryption and the future of security. I hate to be the one to throw cold water on the whole thing—as cool as the new discovery is—but it’s important to separate the theoretical from the practical. ...

and computing efficiency while also lowering storage and transmission costs. This paper introduces a novel method for classifying image features that combines multilevel homomorphic encryption and image data partitioning in an integrated manner. We employ a novel partitioning strategy to reduce computational...

We propose a homomorphic search protocol based on quantum homomorphic encryption, in which a client Alice with limited quantum ability can give her encrypted data to a powerful but untrusted quantum server and let the server search for her without decryp
