Boing Boing 提到在 time.nist.gov 的 port 78 上面有奇怪的東西：Coded messages on US govt timeserver’s nonstandard port，還猜測是 CIA 提供 publickey 給間諜的方式？XD (雖然不是很像 :p)

“In particular, the second number of the second groupings appears simply to be a second count, though what the rest of the numbers mean is unclear. It’s possible that the CIA is sending encryption keys to its spies this way, but it seems unlikely. A few of the numbers in the first grouping barely change at all over repeated pings, which would make it extremely poor key material generator.”
