Great work! This allows to perform arbitrary computation on untrusted devices. However last time I checked computation in this scheme is ridiculously slow: on modern machines, cutting edge implementation of FHE manage to get around 100 integer operations per second. Never the less there have been some brave startups trying to commercialise this technology: https://venturebeat.com/2020/02/18/enveil-raises-10-million-... Other interesting things build on top of FHE: sql database where data and queries are fully encrypted: https://github.com/zerodb/zerodb fully encripted brainfuck vm: https://github.com/f-prime/arcanevm

This is indeed true for our standalone, open source database (https://github.com/zerodb/zerodb). However, it is not the case for our Hadoop scheme (nor our future support for structured database). In these cases, there is no round-tripping required. In fact, it's significantly more performant than existing Transparent Data Encryption in Hadoop, from both a latency and key rotation perspective. We'll likely release a paper describing this new scheme later in the year as well as publish at some conferences.

ZeroDB isn't using CryptDB. And ZeroDB is open source: https://github.com/zero-db/zerodb
