You want to build a hardware device to do block encryption in the cipher block chaining (CBC) mode using an algorithm stronger than DES. 3DES is a good candidate. Figure 7.17 shows two possibilities, both of which follow from the definition of CBC. Which of the two would you choose and why:

April 27, 2020Logical Network DiagramnnThe logical network diagram subsection needs to include, at a minimum, the following:n
- n
- A logical network diagram of the network based on the network requirements (gathered as part of Needs Analysis)
- A description of the logical network diagram and how it’s different parts fir together to form a home network.
n
n
nA logical network diagram resembles “block diagram” of the network connected together. Examples are shown in Figure 1-1 Attached below. In the logical network diagram, each network block is labeled generically (e.g., “router”, “printer”, “TV”, etc) and no manufacturer name and model number needed on the diagram.nnNote that the logical network diagram would contain both LAN and wide-area network connection to the Internet. Discuss how you would connect the home’s LAN to the Internet.nnTECHNOLOGY DESIGN SECTIONnnTechnology design refines the logical network diagram generated and produces a physical design that will meet the requirements. The technology Design section consists primarily of Physical Design. In this report, you only have to produce a Preliminary Physical Design.nnThe Preliminary Physical Design needs to include, at a minimum, the following:nn- Exact configuration of each piece of hardware (e.g., router, printer, TV, etc.) such as manufacture’s names and models, and brief description (in your own words with citations and references) of each piece.nnCOST ASSESSMENT SECTIONnnAfter you have gathered the exact configuration (manufacturer’s name/model number) of each piece of hardware (and software), present a detailed cost estimate of the entire network. The cost assessment section should include a detailed cost assessment of the network. Including cable, hardware, software, and labor. (Assume that 300ft. of cable is needed for the home network.)nnLabor is an important component of cost, so include cost of labor required to install the network. Use a planning figure of $300/person-hour and estimate the cost of labor required to implement the network.nnIn addition, include the ongoing, operational cost of the network (such as monthly Internet Service Provider free or any periodic maintenance cost) for three years. In other words, present both initial, fixed cost of the network and the ongoing, operational cost of operating the network. An explanation of different cost items is required.nnNotesnnAs with any real-life problem with ambiguities or unsolved considerations, you must make your own assumptions, but be sure to explicitly state any assumptions. Feel free to find materials that support your recommendations.
