| | Today we will see how to use the analysis of the multiplicative weights algorithm in order to construct pseudorandom sets. The method will yield constructions that are optimal in terms of the size of the pseudorandom set, but not very efficient, although there is at least one case (getting an ``almost pairwise independent'' pseudorandom generator)...

| | The ``probabilistic method'' is the art of applying probabilistic thinking to non-probabilistic problems. Applications of the probabilistic method often feel like magic. Here is my favorite example: Theorem (Erdös, 1965). Call a set $latex {X}&fg=000000$ sum-free if for all $latex {a, b \in X}&fg=000000$, we have $latex {a + b \not\in X}&fg=000000$. For any finite...

| Recently, it occurred to me that there wasn't a good, focused resource that covers commitments in the context of asymmetric cryptography. I had covered confused deputy attacks in my very short (don't look at the scroll bar) blog post on database cryptography., and that's definitely relevant. I had also touched on the subject of commitment...
