| Dec 1, 2019 at 1:46 | comment | added | Squeamish Ossifrage | If $p$ is prime and large enough, the difference between picking $x$ uniformly at random from $\mathbb Z_p$ vs. $\mathbb Z_p^*$ is essentially immaterial because the probability of picking $0$ is negligible. | |
| Dec 1, 2019 at 1:44 | comment | added | Squeamish Ossifrage | In your second paper, on p. 1312, §2.1 ‘Notation’, it says: In this paper, $x \in_R S$ denotes the operation of picking an element $x$ at random and uniformly from a finite set $S$. | |

Some authors may write $\in_R$ to mean ‘randomly chosen from’, while others use $\xleftarrow\$$ for that, but it's not a widely used standard notation, so it's hard to say without context. Most authors will define what they mean because it's not standard. (That said, $\mathbb Z_p^*$ pretty much always means the set of units in the ring $\mathbb Z/p\mathbb Z$ of integers modulo $p$, i.e. nonzero elements coprime with $p$, so it might be used without definition even though sometimes $\mathbb Z_p$ means the $p$-adic integers in other contexts.) | |
