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) assumption, Saha and Koshiba proposed a practical approach—SK17—in [NBiS2017], ...
Homomorphic encryption and secure comparison We propose a protocol for secure comparison of integers based on homomorphic encryption. We also propose a homomorphic encryption scheme that can be used i... Ivan Damgrd,M Geisler,Mikkel Krigaard - 《International Journal of Applied Cryptography》 被引量...
Homomorphic encryptionis a form of encryption that allows computation on ciphertexts. And the decrypted result matches the result of the operations as if they had been performed on the plaintext. To reduce the communication overhead and computation overhead, homomorphic encryption is chosen to encrypt...
Keywords: cross-border; homomorphic encryption; privacy protection; data transmission; blockchain1. Introduction In the context of economic integration, cross-border data flow has become a key driver of international business, technological innovation, and global cooperation. With the development of digiti...
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. ...
Since all the operations in SIFT must be moved to the encrypted domain, we propose a homomorphic encryption-based secure SIFT method for privacy-preserving feature extraction and representation based on Paillier cryptosystem. In particular, homomorphic comparison is a must for SIFT feature detection ...
To avoid the leakage of patient information and diagnosis results in electronic health data (EHRs) in the process of anomaly detection, a privacy protection model for EHRs' anomaly detection based on CKKS fully homomorphic encryption of sensitive data of hospitals and patients is proposed. The EHRs...
It seems to be impossible to find a working solution for less-than / greater-than comparison for holomorphic encryption using Microsoft SEAL library, and the library does not seem to provide such functionality. The research papers provide only theoretical approaches without sample codes. Is there ...
It contains a Homomorphic Re-Encryption Scheme (HRES), which extends PHE from a single-user system to a multi-user one by offering ciphertext re-encryption to allow multiple users to access processed ciphertexts. With this way, it achieves flexible and secure access control over encrypted data ...
