I'm reading this paper  and I can't translate a sentence to Spanish (well, I'm not pretty sure). The sentence is: "the scheme is correct if the verification algorithm accepts when interacting with the valid prover". I've tried this translate "El esquema es correcto, si el algoritmo de verificación es aceptado cuando interactúa con el proveedor"
P.D The author is Asian and therefore I'm not secure if the sentence is correctly English written. So if the grammar it's ok, can someone explain where to read about this conjugation?.
