    Apple's corecrypto library (scroll way down on developer.apple.com/security/) contains both ccbfv (BFV implementation) and cche (BGV/BFV). Does anyone have any idea what these might be used for? (or why there's two different BFV implementations?)
    A screenshot of the corecrypto library's readme document opened in an editor, showing a list of the library's modules. The term "homomorphic encryption" is being searched for and highlighted twice, once in the description of the "ccbfv" module, which is described simply as "BFV homomorphic encryption scheme", and once within the description of the "cche" module, which reads "Homomorphic Encryption supporting the BFV and BGV schemes".

    Great Introduction to HELayers (tensor tiling for FHE) by Hayim Shaul from @IBMResearch today on the last day of @acm_ccs in LA!
    Speaker standing in front of a projected slide. The slide says "Summary - Haiku Version" and "Pack naively - slow / Write packing-oblivious / Now the code is fast"

    If you want to get an idea what the DARPA DPRIVE program on FHE accelerators is all about, this paper is a great introduction to the power (and challenges!) of dedicated HE accelerators:

    Fully Homomorphic Encryption (FHE) allows computing on encrypted data, enabling secure offloading of computation to untrusted serves. Though it provides ideal security, FHE is expensive when...

    Great(?) to see FHE make an appearance at CFAIL!

    Really cool to see Google get in on FHE and especially FHE compilers! My "update SoK benchmark repo" list just got another item added to it✨

    Big news today! 🚨 We're releasing a first-of-its-kind transpiler to make it radically easier to use 🔐 fully homomorphic encryption🔐! Put regular C++ code in, get FHE-ready C++ code out. Magic ✨ Check our our code! Or keep reading for more info 😀 github.com/google/fully-h…
