Question

Using pseudoprimes, Carmichael's rule, and Miller's Test how would I go about solving Section 6.2 question 1

The important point
is that both results indicate that it is possible to
only O(log, n)k) bit operations, where k is a positive integer. (Also, the recent resug
a
0 (log, n)k) bit operations.) This contrasts strongly with the problem of factori
The best algorithm known for factoring an integer requires a number of bit operat .
factored, whereas primality testing seems to require only a number of bit operatione
less than a polynomial in the number of bits of the integer tested. We capitalize on thi
difference by presenting a recently invented cipher system in Chapter 8.
6.2 EXERCISES
1Show that 91 is a pseudoprime to the base 3.
2. Show that 45 is a pseudoprime to the bases 17 and 19.
Show that the even integern=
2 (mod n). The integer 161,038 is the smallest even pseudoprime to the base 2.
161,038 = 2 · 73 · 1103 satisfies the congruence 2" =
4. Show that every odd composite integer is a pseudoprime to both the base 1 and the base -1.
