At 1000 members a DCGKA key update (when the group membership changes) is ~300kb. So, equivalent to someone sending a small image, which they probably do very frequently.
- kitkat_new 4y agoper device? what about the computational costs involved (which may require wasm/js)?
- ianopolous 4y agoDon't get me wrong, FR-CGKA looks cool. I hadn't seen it yet, and am still reading it. Not sure why wasm/js is relevant to the discussion.
- kitkat_new 4y agowell, encryption needs computational resources; you have to expect higher overhead when you do encryption in the web compared to native code e.g. in Rust or C. It kind of is the upper bound of slowness ;)
- ianopolous 4y agoI thought the selling point of wasm was close to native speed. :-) If something is important browsers can always add it to webcrypto anyway.
