One-time pads are only useful if they're not re-used.
Or are you suggesting that the high-latency link is higher throughput, and provides constant gigabytes of pad material? (Eg, stream cipher)
- ah- 12y agoThere is already a second fibre link in these setups that has higher throughput and not much more latency.
- cpwright 12y agoA microwave link is much lower bandwidth than the optical fiber that already exists to connect the two points (you can't rely solely on microwave, you need fiber to back it up when it rains or is cloudy, etc.). Also, depending on the market, you're only trading 8 or so hours a day. You can just send the pad during the 16 hours of the day while the link is otherwise unused.
