FHEllo, world! FHE Community Workshop

February 21, 2024

Workshop, enCRYPTON: Summer School on Cryptographic Solutions for Privacy Enhancing Technologies, Sabanci University, Istanbul, Turkey

I had the pleasure of participating in the FHEllo World! workshop, a community-oriented online event focused on Fully Homomorphic Encryption (FHE). During the workshop, I presented a talk on the OpenFHE library, an open-source platform that empowers developers to employ FHE in their privacy-concerned applications. My talk explored the library’s capabilities and highlighted its potential to revolutionize how we handle sensitive data in various applications.

enCRYPTON: Summer School on Cryptographic Solutions for Privacy Enhancing Technologies

August 28, 2023

Workshop, enCRYPTON: Summer School on Cryptographic Solutions for Privacy Enhancing Technologies, Sabanci University, Istanbul, Turkey

I participated in this workshop as an instructor and gave five lectures on the following topics:

OpenFHE: Open-Source Fully Homomorphic Encryption Library

November 07, 2022

Conference Paper Presentation, WAHC 2022 – 10th Workshop on Encrypted Computing & Applied Homomorphic Cryptography, Los Angeles, California

In this talk, I introduced OpenFHE, an open-source library for secure computation on encrypted data. OpenFHE includes implementations of several modern cryptographic techniques that enable computing on private data without disclosing it to any party.

Fully Homomorphic Encryption on GPUs: Design, Implementation & Performance Evaluation

May 03, 2022

Research Seminar, Invited Talks on Emerging Topics in Secure Computing, Virtual

This invited talk presented my research on accelerating homomorphic encryption (FHE) on Graphical Processing Units (GPUs). Focusing on RLWE-based FHE schemes, I discussed their design, implementation, and performance optimization on GPU platforms. My key contributions include:

Privacy-Preserving Computing

October 03, 2021

Talk, Cyber Wales Cluster Webinar in the Middle East, Abu Dhabi, UAE

In this talk, I introduced three emerging technologies that have the potential to revolutionize outsourced computing: Multi-Party Computing (MPC), Fully Homomorphic Encryption (FHE), and Functional Encryption (FE). I presented real-world examples of their typical use cases, capabilities, and limitations.

Trustless Computing on Encrypted data

July 01, 2020

Talk, National Cybersecurity Research and Development (NCR) Program, Singapore

In this talk, I provided an overview of fully homomorphic encryption (FHE) as a privacy-enhancing technology (PET) for enabling secure computation on encrypted data.

High-Performance FV Somewhat Homomorphic Encryption on GPUs: An Implementation using CUDA

September 10, 2018

Conference Paper Presentation, Conference on Cryptographic Hardware and Embedded Systems, Amsterdam, The Netherlands

In this talk, I presented my work on accelerating a fully homomorphic encryption (FHE) scheme, the fully-RNS variant of the BFV scheme, using GPUs.

Faster Number Theoretic Transform on Graphics Processors for Ring Learning with Errors Based Cryptography

July 31, 2018

Conference Paper Presentation, 2018 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI),

In this talk, I presented a GPU-accelerated variant of the Number Theoretic Transform (NTT) known as the Generalized Discrete Galois Transform (DGT).

Efficient Polynomial Multiplication via Modified Discrete Galois Transform and Negacyclic Convolution

April 06, 2018

Conference Paper Presentation, Future of Information and Communication Conference, 2018, River Valley, Singapore

In this talk, I presented a generalization of the DGT transform over non-Gaussian primes and applied it to accelerate polynomial multiplication in power-of-two cyclotomic rings for lattice-based cryptography.
