This Week’s Cool Product

Hex-Five Security’s MultiZone product is a software layer that uses hardware to enforce high security when using untrusted code. Currently RISC-V versions are available.

It’s a small (under 2 KB) bit of code that is formally verifiable. That’s a big selling point when pursuing a Common Criteria security standard. As I understand it, the product enforces separation zones to keep bad actors out of others’ sandboxes, which sounds like the Common Criteria’s separation kernels.

A datasheet is here. It’s free for non-commercial use.

Note: This section is about something I personally find cool, interesting or important and want to pass along to readers. It is not influenced by vendors.
