Hardware Solution for Cloud Data Security? Ascend

This may, in the long term, represent one way in which security for cloud-resident data-at-rest becomes manageable and cost-efficient.

Hardware Trick Could Keep Cloud Data Safe - IEEE Spectrum:

Dubbed Ascend, the component hides the way CPUs request information in cloud servers, making it immensely difficult for attackers to glean information about the data stored there. Such a hardware-reliant scheme is an unusual proposition in the realm of cloud security, which is dominated by software solutions.
The researchers assume that sensitive data on cloud servers is already encrypted—typically the first line of defense when it comes to data security. Ascend goes a step further, its designers say, by dealing with sneak attacks that can happen through various so-called side channels. In a side-channel attack, an observer measures things like computation time, memory traffic, and power consumption to infer the behavior of a program running on that hardware, and from that the watcher can glean some information.
