IBM's new mainframe keeps everything encrypted, all the time

From Engadget - July 16, 2017

The new platform can also "self-destruct" encryption keys the moment there's any tampering, and quickly encrypts the programming interfaces that tie apps and services together. And the Z is faster overall, regardless of the task at hand: there's three times the memory (a hefty 32TB), three times faster input/output and much lower lag when talking to a storage area network. The hardware should juggle many more transactions (like purchases at an online store) even as it boosts their overall security.

Naturally, there are catches to this utopian vision of internet security. While IBM plays an important role in online commerce (its transaction engine handles 87 percent of credit card payments), many companies would likely have to upgrade before you'd see the benefit. Any mass migration would probably take years, if it happens at all. And of course, IBM's solution does not stop hackers from taking data -- it just prevents them from reading that data. There's a chance, however slim, that the most determined perpetrators will find a way to decrypt content once they have it.
