> Some of the existing tools, such as homomorphic encryption or secure enclaves have performance unsuited to scalable encrypted search, require proprietary hardware, or have uncertain security properties. I don't think this is exactly homomorphic. I hope they put out a whitepaper so researchers can properly evaluate its security.
