It really highlights the amazing security level of one time pads, that they can be comfortably doing secret announcements on a public radio channel with provably perfect security. (Assuming an adequate PRNG--for such small messages they could easily be using a hardware PRNG; I wonder.) Only issue is that you have to have all of your recipients keep track (and not leak) a pad that is at least as long as the data you intend to send.
