Cross-row dump capability

Is randomized row-swap secure or scalable?

A recent work, called Randomized Row-Swap (RRS), proposed proactively swapping aggressor rows with randomly selected rows before an aggressor row can cause Row Hammer. Our paper observes that RRS is neither secure nor scalable. We first propose the ‘Juggernaut attack pattern’ that breaks RRS in under 1 day.

What is scalable and secure row swap (SRS)?

Scalable and Secure Row-Swap (Scale-SRS) aims to reduce the swap rate and mitigate the memory bandwidth overheads from swaps while providing years of security. To this end, Scale-SRS uses the observation that, even during an attack, the original locations of only a few aggressor rows receive multiple swaps.

When does a steam dump end in a turbine runback?

On a load rejection resulting in a turbine runback, the steam dump terminates when the reactor power matches the turbine load and the temperature error is within the maneuvering capability of control rods.

Can a swap-count based attack detection mechanism detect outlier rows?

However, our swap-count-based attack detection mechanism can detect outlier rows, and then additional activations can be prevented by simply pinning these outliers in the Last Level Cache (LLC) for the rest of the refresh period (using <6% of the LLC).

What is load rejection steam dump controller?

At the same time, the load rejection steam dump controller regulates the position of steam dump valves to prevent a large increase in reactor coolant temperature and to keep an artificial load on the primary loop to reduce the impact of the transient on the RCS.

How do I Break a migration into multiple tasks using row filtering?

To break the migration into multiple tasks using row filtering, use a key or a partition key. For example, if you have an integer primary key ID from 1 to 8,000,000, you can create eight tasks using row filtering to migrate 1 million records each. Open the AWS Management Console. Choose Tasks, and create a new task.
