Let the modulus be p = 23. Bob sends to Alice the value B = 9. Alice’s secret value is a = 10. Compute the secret key kAB to be shared between Alice and Bob. (Explain your computation.) Tip: Perform computation of kAB as it is to be done by Alice. (For completeness, we note that the generator g = 6, but you do not need it for this computation.)
Homework Answers
Solution:
=>Symmetric key cryptography is used.
=>Modulus(p) = 23
=>Bob's public key(B) = 9
=>Alice secret number(a) = 10
Explanation:
Calculating the secret key kAB:
=>Secret key(kAB) = (B)^a mod p
=>Secret key(kAB) = (9)^10 mod 23
(9^5 mod 23 = 8 so 8*8 mod 23 = 18)
=>Secret key(kAB) = 18
=>Hence the shared key between Alice and Bob = 18
I have explained each and every part with the help of statements attached to the answer above.

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...

Question 2: You are Alice. Bob publishes his ElGamal public key (q, a, ya) = (101, 2, 14). You desire to send the secret message “CALL ME” to Bob. Using the equivalence A = 01, B = 02, and so on up to Z = 26, you encode the message into the number 03 01 12 12 13 05. Regarding each of these two-digit numbers as a plaintext block, compute the message that you will send to Bob using his...

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...

2. Alice is a student in CSE20. Having learned about the RSA cryptosystem in class, she decides to set-up her own public key as follows. She chooses the primes p=563 and q = 383, so that the modulus is N = 21 5629. She also chooses the encryption key e-49. She posts the num- bers N = 215629 and e-49 to her website. Bob, who is in love with Alice, desires to send her messages every hour. To do so,...
