Scalar Product Lattice Computation for Efficient Privacy-Preserving Systems

نویسندگان

چکیده

Privacy-preserving (PP) applications allow users to perform online daily actions without leaking sensitive information. The PP scalar product (PPSP) is one of the critical algorithms in many private applications. state-of-the-art PPSP schemes use either computationally intensive homomorphic (public-key) encryption techniques, such as Paillier achieve strong security (i.e., 128 b) or random masking technique high efficiency for low security. In this article, lattice structures have been exploited develop an efficient system. proposed scheme not only computation compared but also provides a degree against quantum attacks. Rigorous and privacy analyses provided along with concrete set parameters 128-b 256-b Performance analysis shows that at least five orders faster than twice existing randomization Also requires six-time fewer data randomization-based communications.

On Private Scalar Product Computation for Privacy-Preserving Data Mining

In mining and integrating data from multiple sources, there are many privacy and security issues. In several different contexts, the security of the full privacy-preserving data mining protocol depends on the security of the underlying private scalar product protocol. We show that two of the private scalar product protocols, one of which was proposed in a leading data mining conference, are ins...

A New Efficient Privacy-Preserving Scalar Product Protocol

Recently, privacy issues have become important in data analysis, especially when data is horizontally partitioned over several parties. In data mining, the data is typically represented as attribute-vectors and, for many applications, the scalar (dot) product is one of the fundamental operations that is repeatedly used. In privacy-preserving data mining, data is distributed across several parti...

Efficient scalar product protocol and its privacy-preserving application

Scalar product protocol aims at securely computing the dot product of two private vectors. As a basic tool, the protocol has been widely used in privacy preserving distributed collaborative computations. In this paper, at the expense of disclosing partial sum of some private data, we propose a linearly efficient even-dimension scalar product protocol (EDSPP) without employing expensive homomorp...
