Now available on eprint is: "How to Enumerate Your Keys Accurately and Efficiently After a Side Channel Attack".
This paper by Bristol Crypto shows how the key ranking and key enumeration problem can be framed as an optimisation problem, the knapsack problem, to allow extremely quick and efficient solving. The paper details a novel graph algorithm which enables the ranking of keys accurately and nearly instantly, and provides best in class performance results for key enumeration. The algorithm can easily be fully parallelised, with excellent scaling results as more processors are used.
For full details, see the associated blog article on the Silent website, here. The parallel key ranking algorithm has been developed into a public API, which is available on the tools page.
