What is Homomorphic Encryption?

This post is part of our Privacy-Preserving Data Science, Explained series.

What is the Paillier cryptosystem?

This post introduces the Paillier cryptosystem, which is a partial homomorphic encryption scheme. In a subsequent post we’ll see how this can be used as the basis for a private set intersection protocol.

From Fully Homomorphic Encryption to Silicon - What is Microsoft's HEAX?

In this blog, Sadegh Riazi explains Microsoft's Project HEAX. One of the main obstacles in leveraging Fully Homomorphic Encryption at large-

Build an Homomorphic Encryption Scheme from Scratch with Python

This blog post aims at explaining the basic mathematical concepts behind most of today's homomorphic encryption schemes, and then build upon this to implement our own scheme (similar to BFV) from scratch using Python.

Homomorphic Encryption in PySyft with SEAL and PyTorch

In this post we showcase a new tensor type that leverages the CKKS homomorphic encryption scheme implemented on the SEAL Microsoft library to evaluate tensor operations on encrypted data.
