Dear Konstantinos Birkos I feel interest about your thoughts.
Key refreshment is an important issue to promise security of P2P overlay network as well as other types of networks. Cost of key refreshment mechanism, the architecture of key management, etc, lots of work should be done. 2010/2/25 Konstantinos Birkos <[email protected]> > Dear all, > > I would like to discuss the possibility of periodically refreshing the > keying material of the participating peers in the overlay as well as > certificate revocation in case malicious activity is detected. > I am talking about each peer periodically creating new public/private key > pairs and producing or receiving new certificates that bind its NodeID to > the new public keys.
