“I think I see now where that guy was coming from, but he had me going for a minute there,” says Miss deLimit. She is discussing a prototype of display output, one designed by the systems analyst that she has just seen. “I mean, I never considered it a problem before if even as much as 20 percent of the total class size couldn’t be fit into a class,” she says. “We know our classes are in demand, and because we can’t hire more faculty to cover the areas we need, the adjustment has to come in the student demand. He’s got it highlighted as a problem if only 5 percent of the students who want a class can’t get in, but that’s okay. Now that I know what he means, I’ll just ignore it when the computer beeps.”
a. In a sentence or two, describe the problem Miss deLimit is experiencing with the display output. b. Is her solution to “ignore the beeps” a reasonable one given that output is in the prototype stage? c. In a paragraph, explain how the display output for this particular problem can be changed so that it better reflects the rules of the system Miss deLimit is using.
Suppose a web client and web server for a popular shopping web site have performed a key exchange so that they are now sharing a secret session key. Describe a secure method for the web client to then navigate around various pages of the shopping site, optionally placing things into a shopping cart. Your solution is allowed to use one-way hash functions and pseudo-random number generators, but it
cannot use HTTPS, so it does not need to achieve confidentiality. In any case, your solution should be resistant to HTTP session hijacking even from someone who can sniff all the packets. What will be an ideal response?
