MaskedLARK: Why floating point secret sharing? #26

As far as I can tell, the MaskedLARK proposal uses float secret sharing. Why was this chosen over integer secret sharing which is conceptually much simpler?

I think Charles answered this verbally in a call after this issue was posted -- in theory, we should be able to work on finite rings, which includes FP values. In practice, yes, we'll plan on actually implementing these primarily as bounded integers. We'll work to clarify this in subsequent proposals.
