Ok, lets look at the operations. Sign: $s = g * r^{f(t,m)} \pmod n$ This is an assignment. You compute $(g * r^{f(t,m)}) \mod n$ and assign the resulting value to $s$. If you have a multiplication $(a \cdot b) \mod n$, this is equal to $((a \mod n)\cdot (b \mod n)) \mod n$. See for instance here. Verification: $s^e = i * t^{f(t, m)} \pmod n$ This is no ...
