Question
Let $p=29$ and $q=31$ so that $m=899$, and let $e=101$. Find$$d=e^{-1} \bmod \varphi(m)$$Then let $x=555$ and compute $y=x^e \bmod m$ and $z=y^d \bmod m$.
Step 1
Since \( m = pq = 29 \times 31 = 899 \) and \( p \) and \( q \) are prime, \( \varphi(m) = (p-1)(q-1) = 28 \times 30 = 840 \). Show more…
