[Cryptography] On Security Architecture, The Panopticon, And "The Law"

[James A. Donald]

The old Skype system was user friendly and offered end to end 
encryption, except that the central authority could easily mim someone, 
and except that it was a closed source implementation of a closed source 
protocol, thus could be quietly changed without telling anyone.

And, of course, was quietly changed without telling anyone.

Solution to mim by central authority: some kind of distributed, append 
only, database, such that if the central authority mims someone, it 
faces a significant risk of detection.

However, distributed append only data base not quite as easy as it sounds.
