Step 1: Establish a target audience and scope for your presentation. Select a real or hypothetical business engaged in e-business and outline its central offerings and/or services. Next, outline the categories of information that may require cryptography applications. This will provide focus to your research. Optionally, you can also select an industry.
Step 2: Assume you are the Senior Director of Security for the organization identified in Step 1. You have been asked to provide an executive briefing to middle and upper management on the topic of cryptography and how it should be applied in this environment. Think about what is important and/or interesting to the management team.
