🗓️ The next FHE.org meetup has been scheduled for next week, Thursday, Jan 30th at 2pm CEST (Paris, FR).
This meetup features Philippe Chartier, Senior researcher at Inria, presenting Homomorphic Sign Evaluation with a RNS Representation of Integers.

Abstract
In the context of fully-homomorphic-encryption, we consider the representation of large integers by their decomposition over a product of rings (through the Chinese Remainder Theorem) and introduce a new algorithm for the determination of the sign solely through the knowledge of ring-components. Our implementation with 128 bits of security delivers a correct result and a probability higher than 1-1.e-9 in less than 100 milliseconds for 32-bit integers on a laptop.
About the speaker
Senior researcher at Inria. Previously at Ravel Technologies for the last three years.
