In this hands-on activity, you will work with a simplified – and not very secure – version of one of the most popular public-key systems, RSA public-key encryption system. Like all public-key systems, the keys are derived using a “trapdoor” operation – an operation that is easy to do but difficult to “undo.” In RSA, this operation is the multiplication of 2 large prime numbers: it is easy and fast to multiply the 2 numbers together, but it is significantly more difficult and time consuming to factor the result back into its prime components. In this graded activity, you will use relatively small primes (3-digit #’s) to see how this system works. Use the accompanying Excel file to complete the following steps and submit the Excel/Word file(s) for the questions below.
that’s the intro.
there is the two documents that are related to each other, the word document gives you instructions and some of the results that you get in the excel document should be documented in the word document. at the end, there are 5 questions to be answered.
