CKKS — Addition and Multiplication

Jeremy Kun

Table of Contents This is part of a tutorial series on the CKKS homomorphic encryption scheme. In the last article, we introduced symmetric and public-key encryption and decryption routines, and implemented modular polynomial arithmetic (using NTTs as a black box). This article covers the addition and multiplication operations performed on ciphertexts (without relinearization). Again, if you already know about CKKS, we are still avoiding the RNS form of the scheme and using a 64-bit modulus $Q$, which means that we’re momentarily ignoring cryptographic security.

Test README with Users and Docker: Two-Layer Verification

SitePoint

Verify your project setup documentation using a two-layer testing workflow: automate commands in a clean Docker container to catch mechanical setup errors, then observe a real user think aloud to identify missing prerequisites and unclear steps.

New website: estimating human cryptanalytic work

Matthew Green

This is not so much a full post as it is an advertisement. I’ve been working with Claude and GPT 6 Astra to conduct a survey of historical cryptanalysis results, in an effort to determine how many human-hours have been spent attempting to cryptanalyze the problems we use in public-key encryption schemes. This is work … Continue reading New website: estimating human cryptanalytic work →
