Alice wants to send to all her friends, including Bob, a message using the RSA cryptosystem. She chooses secret primes p 17, q = 29 and computes n = pq. (a) In how many ways can Alice choose an encryption key (n, e) with 1 < e < (p- 1)(q- 1)? (b) What is the smallest such e > 1 that Alice can choose? What is the correspond- ing decryption key d?
