Method Details

Compute share_a >= share_b.

Both arguments must be from the same field. The result is a GF256 <viff.field.GF256> share.

Decorators:

Warning: The result type (viff.field.GF256) is different from the argument types (general field elements).

Defined by:

(x, X) `diamond` (0, Y) = (0, Y)
(x, X) `diamond` (1, Y) = (x, X)
