Question: Alice sets up an RSA cryptosystem with modulus n = pxqwith large primes p andq, and the key pair ( e , d ) .

Alice sets up an RSA cryptosystem with modulus n =pxqwith large primes p andq, and the key pair (e, d). Then Alice wishes to strengthen the security of hthe size of 1 m. So she uses n'=2n as the new modulus for the cryptosystem.on the system after using the new modulus? Does the change of modulus strengthen the systemsecurity?Solution:
Alice sets up an RSA cryptosystem with modulus n
