A potential concern - does this system implement forward secrecy? Is that even possible?
The threat I'm thinking of is some organisation that is able to crack the private key at some point in the future and therefore able to work out where you have been in the past.
Of course, the phone's location in the recent past is exactly what this system is designed to produce. Would it be possible to rekey the connection on a regular/opportunistic basis?
