- Were you able to go to college with Grace?Charlie was just getting ready to head home when the phone rang. Caller ID showed it was Peter. “Hi, Peter,” he said into the receiver. “Want me to start the file cracker on your spreadsheet?” “No, thanks,” Peter answered, taking the joke well. “I remembered my passphrase. But I want to get your advice on what we need to do to make the use of encryption more effective and to get it properly licensed for the whole company. I see the value in using it for certain kinds of information, but I’m worried about forgetting a passphrase again or even worse, that someone else forgets a passphrase or leaves the company. How would we get their filesback?” “We need to use a feature called key recovery, which is usually part of PKI software,” said Charlie. “Actually, if we invest in PKI software, we could solve that problem as well as several others.” “OK,” said Peter. “Can you see me tomorrow at 10 o’clock to talk about this PKI solution and how we can make better use of encryption?” (Case Study…What am I doing wrong if I want to acquire my access code for this book? I was wondering if there was any way that you could either help me discover it or give me information on how to find it on my Yuzu account.
- Respond to the following in a minimum of 175 words: Discuss a cryptography attack scenario. Choose an attack and explain how it works. Be sure to choose one that hasn’t been mentioned by another classmate. What countermeasures would you apply? How do the countermeasures you would use compare to those your classmates recommended for the attacks they chose? What do those similarities or differences tell you about fighting these types of attacks?What are the specific goals that we want to accomplish with this authentication procedure? Give an explanation of both the positives and negatives associated with each authentication technique that you've investigated.When do you think you'd want to employ asymmetric encryption?
- How certain are you that the information won't be used against you?Is there any chance that authentication might help us reach our goals?Here, we'll take a look at the pros and cons of many authenticator methods and see how they stack up against one another.Is there any chance that authentication might help us reach our goals?
