RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone. The other key must be kept private. The algorithm is based on the fact that finding the factors of a large composite number is difficult: when the integers are prime numbers, the problem is called...

In public key cryptosystems, the RSA is the most commonly used algorithm. Answer the following questions: - 1. In the RSA algorithm, what is the security flaw with choosing e = 1 for the public key? (Hint: the RSA formula for encryption is c = M e mod n). 2.You are given a cipher text C=10 by a user whose public key is e=5, n=35. Break the code.

After looking at the RSA algorithm for asymmetric key encryption and decryption. And after looking at Diffie-Hellman Exchange and at the Elgamal encryption scheme that can use the key derived from the exchange. State the justification for having this alternate mechanism when RSA is already well established. Consider the security and the computational aspects of the schemes. Be as specific as possible.
