Those are probably LAI locks but the restricted 1/2 moon key is the best design to get, whether from LAI or Abloy. Abloy will be more expensive. With these you order from LAI and they give you a key code that only you can reorder. And yes, they are very hard to pick and to drill out. However, they will not stop a determined thief because nothing will if they bring the cutting torch, die grinder, etc.
