PFS

[PeterSurda]

A new address version that contains expiring ephemeral subkeys (which are not a part of the address itself) would allow something like PFS. It requires some design, to make sure they keys are not deleted prematurely for example.

For a proposal, see here: https://www.reddit.com/r/bitmessage/comments/3zzevp/forward_secrecy_for_bitmessage/

There is another proposal in #454 .

It has some interesting ideas, but it requires an extra round trip to set up a session. It also tries to swap old keys with new ones, but I fail to see how old keys are properly destroyed. Security-wise I think it is similar to my current proposal.

Has there been any success in implementing this or any other PFS in bitmessage?
