Detailed Description

Function for obliviously choosing one of the inputs.

Note

D - all protection domains

T - any data type

Parameters

cond	- a boolean scalar
first	- values for true case
second	- values for false case

Returns

one of the input arrays that was obliviously chosen with the condition. if true, array first is returned else second is returned

Leakage

None
