Cryptographic Systems
The Week 10 Critical Thinking assignment continues with the scenario set up for the Critical Thinking assignment in Week 8. You have been hired as the chief officer of information technology at a retail store in Medina City. The store has 5000 customers subscribing to its electronic services, such as the ability to download their monthly statements.
You've been charged with the task of preparing a report about possible cryptographic systems to be considered. You should also select one of the considered systems and recommend it for implementation. Your selection should be strongly justified.
Your well-written paper should meet the following requirements:
wireless networking and unified communication networks please respond to the following1.analyze three enhancements that
Logic bombs, War dialing, Ping of death attack, steganography, RSA scheme, digital signature, A chain of certificates, A certificate revocation list, A trust anchor, asymmetric algorithm used by PGP, IPSec mode, IP virtual Private Networks
For each of the three (3) or more malicious attacks and / or threats that you identified in Assignment 1, choose a strategy for addressing the associated risk (i.e., risk mitigation, risk assignment, risk acceptance, or risk avoidance). Explain your ..

Alice is able to intercept the message, and generates an alternative message that has a hash value that collides with Bob's original hash value. Show a message that Alice may have spoofed, and demonstrate that its hash value collides with Bob's or..
Decrypt the cipher-text c = 12 by using secret key sk = (p, q) = (11, 13), where te corresponding public key is pk = (N, e) = (143, 13).
Based on the understanding of Q4 of Bart B, use the generated keys of Q2 - Part C to encrypt the message of Q1 - Part C using the Simplified DES algorithm.
