Technology-Wise we shall see a migration from erosive intractability to probability enduring entropic advantage ciphers both through classic means and through the looming prospect of Quantum Cryptography.
Application-wise we shall see (i) intensification of use to anywhere data is stored or transported, and (ii) spread of application categories.
We shall see a growing emphasis on end to end encryption, encryption on small end-devices, and on identity based encryption.
New application categories will be led by mistrustful collaboration and by digital transactional tools -- crypto currency.
Tethered Money: Digital Currency & Social Innovation.
The epic battle between governments using cryptography to better observe and better manage their people, and the people using the same technology to push back governmental intrusion -- will continue -- the jury is still out as to who will prevail.
