A subtle point which I don't really explain in the post, since it was initially targeted to people who had done some cryptography with groups before, is that you need to carefully …

That is true. That said, there are few situations where the modulus being used is not a public parameter of a protocol, and it is very difficult to perform operations with a secret…

If you have a random stream of bits, and you use rejection sampling to extract a value from that stream, then you don't reveal any information about the value. At most, you reveal …

It does sometimes get abused, but such abuses fall under wire fraud laws, which carry heavy punishments. So, the legal system is the prevention mechanism for abuse here.

One big difference is the density of the fuel. You can fill a car with gas in under a minute. While fast-charging (like Tesla's super charging) has growing deployment, that's still…

Reading this post, this is actually an explanation of Schnorr signatures, not ECDSA signatures. Bitcoin uses the latter, except for new transactions after the Taproot update, which…

Sleeping just long enough to fill the remaining time-slot for an operation is actually a valid countermeasure; in theory. The problem is figuring out how much sleep is necessary ba…

Author here. To illustrate my point further, let's say that your operation takes either 0.1ms or 0.0ms. If you add in a uniform random delay of 100-1000ms, your expected random del…
