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.

forehand e receiver creates a public key and a secret key as follows. Generate two distinct primes, p andq. Since they can be used to generate the secret key, they must be kept hidden. Let n-pg, phi(n) ((p-1)*(q-1) Select an integer e such that gcd(e, (p-100g-1))-1. The public key is the pair (e,n). This should be distributed widely. Compute d such that d-l(mod (p-1)(q-1). This can be done using the pulverizer. The secret key is the pair (d.n)....

For questions 1 to 4 pick another public health problem that has NOT been discussed in class. 1) Use the internet to find its prevalence in the nation. Write it as a percent of the US population. Include the internet link that reported that number. 2) What do you think is a major cause of this problem? Design a test or survey questions to prove your theory. 3) What can be done to reduce the incidence of this problem? 4)...

The Diffie-Hellman public-key encryption algorithm is an alternative key exchange algorithm that is used by protocols such as IPSec for communicating parties to agree on a shared key. The DH algorithm makes use of a large prime number p and another large number, g that is less than p. Both p and g are made public (so that an attacker would know them). In DH, Alice and Bob each independently choose secret keys, ?? and ??, respectively. Alice then computes...
