Lesson Six - RSA Coding and Current Issues in Cryptography
Objective: 1. The student will understand the method behind RSA coding.
2. The students will share thoughts and do research on some current issues of coding.
Anticipatory Set: Share articles with students on the security issues on the internet and ask students how coding is done today in the current times.
Input:
Methods of Presentation:
- discussion - demonstration - group work
Previous Knowledge
- prime numbers, modular arithmetic, exponentials
Task Components
- TLW learn the method of RSA coding.
- TLW research on the internet and in the library current issues in cryptography.
- TLW demonstrate understand of how RSA works.
Thinking Levels
- Knowledge: recall previous information
- Comprehension: relate concepts to new methods
- Application: see why RSA difficult to break in use
- Analysis: set limits resonable for class
- Synthesis: generate ideas of security and protection
- Evaluation: complete worksheet and write paper on issues
Modeling
- Teacher will demonstrate the way to code using RSA.
- Teacher will review any necessary information so students understand work.
Check for Understanding
- Ask questions of students as work goes on.
- Have students work together in groups.
Guided Practice
- TLW complete work in groups
- TLW talk with peers about current issues in coding led by the teacher
Independent Practice
- TLW write paper after doing reserch on issues in crypotgraphy to wrap up unit.
