Alan and Bill agree (through a public exchange) on using the Diffie-Hellman algorithm to create a common secret key. They also agree on two public numbers: q (large prime number), (generator mod q): q = 13, = 3 Alan generates a random RA =11. Bill generates a random RB =13. (a) What is the SA Alan sends to Bill? (i.e. SA =? (3 points) (b) What is the SB Bill sends to Alan? (i.e. SB =? (3 points) (c) Show how Alan can calculate to obtain a common secret key. What is the common secret key? (4 points) (d) Show how Bill can calculate to obtain a common secret key. What is the common secret key?

5. Diffie-Hellman key exchange. Alice and Bob use Diffie-Hellman key exchange protocol to communicate in secret. They publicly announce a prime number p = 23 and a primitive root r = 5 under modulus 23, Alice picks a secret key a-6 and in turn receive the key ß-19 from Bob (a.)

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...

Diffie-Hellman Key Exchange: Alice and Bob wants to agree on a key. First, both agree on p = 23 and g = 5 which is public. Alice chooses her secret key xA = 8 and Bob xB = 14. (a) What will be the shared secret key? (b) DH Key exchange is vulnerable to the following attack. Adversary sits between Alice and Bob, intercepting all messages. Alice and Bob thinks they talk to each other while in fact both talking...

The Diffie-Hellman key exchange is vulnerable to the following type of attack. An opponent Carol intercepts Alice’s public value and sends her own public value to Bob. When Bob transmits his public value, Carol substitutes it with her own and sends it to Alice. After this exchange, Carol simply decrypts any messages sent out by Alice or Bob, and then reads and possibly modifies them before re-encrypting with the appropriate key and transmitting them to the other party. Choose all...

I have to modify a server program and chat program to work as the following instructions but I am completely clueless as to where to start. I'd appreciate any help on how to atleast get started. This must be done in java. Diffie-Hellman Two parties use a key agreement protocol to generate identical secret keys for encryption without ever having to transmit the secret key. The protocol works by both parties agreeing on a set of values (a) and (q)....
