Question1: Alice and Bob use the Diffie–Hellman key exchange technique with a common prime q = 1 5 7 and a primitive root a = 5. a. If Alice has a private key XA = 15, find her public key YA. b. If Bob has a private key XB = 27, find his public key YB. c. What is the shared secret key between Alice and Bob?

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...

4. Supppose Alice and Bob are using the prime p = 1451 and the base g = 2 for an ElGamal cryptosystem. (a) Alice chooses a = 753 as her private key. What is the value of her public key A? (b) Now suppose Bob chooses b = 500 as his private key, and thus his public key is 464 mod 1451. Alice encrypts the message m = 284 using the ephemeral key k=512. What is the...

5. Alice wishes to send the message m4 to Bob using RSA encryption. She looks up Bob's public key and finds that it is (n-55. c= 3 (a) Specify exactly what information Alice sends to Bob (b) What is Bob's private key? Show how he would use it to recover Alice's message (c) Explain why Bob should never use this choice of public key in real life.

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...

Chinese celebrity measures up in each of those attributes.

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
