Digital Signature using the RSA algorithm:  Alice is sending an integer value mA = 3 to Bob with RSA signing. Alice's public key and private key are (5, 14) and (11, 14). Alice first releases her public key to public.  1) How to calculate the signature sig(mA).   2) Later, Bob receives (mA, sig(mA)). Show how Bob verifies mA is from Alice. 3) Charlie, an attacker, sends a message mC = 4 to Bob and lets Bob believe mC is from Alice. mC’s digital signature sig(mC) is calculated using Charlie’s private key (7, 15). Show how Charlie computes sig(mC), and how Bob verifies whether it is from Alice or not (hint: Bob will use Alice’s public key).

Suppose you and your friend would like to use Diffie-Hellman key exchange system to exchange a keyword. Both of you have decided to use the following p = 4138327577, q = 3742197127.If you decide b = 1767005, and your friend has picked a number a that you don’t know. But you havereceived q a mod p from your friend, and the number is 980246808. Find out the common shared key.

For the following NFA M. 1 start 90 qi q2 From the list below, select all computations of M on the string 100. O go → go q1 → 92 92 qo → qo → q1 → q1 q0 → q0 → qi → q1 → q2

An argument is expressed in English below. The domain is the set of people attending a party. Every person who was late to the party left the party early. There is a person who was late to the party and was not happy. .. There is a person who left the party early and was not happy. The form of the argument is: x (P(x) → Q(x)) 3X (P(x) ^ ¬R(x)) .: 3x (Q(x) ^ ¬R(x)) Select the definitions for predicates P, Q, and R. P(x): Pick Q(x): Pick R(x): Pick

How do I make this java encryption and decryption show different letter and not use the same words in a word E.g. Message: Character Message encrypt: Hmfwfhyjw Message decryption: Character So the letter a are switched out with f. I would all letters to be unique and not be the same Same with r
