Chapter 1, Problem 1.44(choose chapter or problem)
Alice and her three friends are all users of the RSA cryptosystem. Her friends have public keys(Ni, ei = 3), i = 1, 2, 3, where as always, Ni = piqi for randomly chosen n-bit primes pi, qi. Showthat if Alice sends the same n-bit message M (encrypted using RSA) to each of her friends, thenanyone who intercepts all three encrypted messages will be able to efficiently recover M.(Hint: It helps to have solved problem 1.37 first.)

ANSWER:Step 1 of 2
The RSA encryption scheme is typically used to encrypt and decrypt electronic data. It is an asymmetric cryptographic algorithm.RSA also known as public key cryptography. This is because one of the keys can be provided to anyone.
