CYBR 3500 — Cryptography Applied

Course description

Symmetric and public-key cryptography, hashing, key exchange, digital signatures, and certificates — how they work, how they fail, and how to use libraries correctly.

Cryptography Applied is an advanced undergraduate course in Cybersecurity (CYBR 3500), carrying 3 credits, and is typically offered fall.

Prerequisites

MATH 2100. Prerequisites are enforced at registration; a registration override from the department is required to enroll without them. This course in turn serves as a prerequisite or a recommended background for later courses in the sequence.

What you will be able to do

By the end of the course, a student who does the work should be able to:

• Explain the core concepts, terms, and methods of cryptography Applied.
• Analyze and solve open-ended problems in cybersecurity, justifying the approach and the result.
• Select and apply appropriate tools, models, or frameworks, and evaluate how well they fit the situation.
• Communicate technical findings clearly in writing and in discussion, for a specified audience.

Each section publishes its own specific, measurable outcomes on the syllabus; these are representative.

How it is taught

Advanced coursework that combines focused instruction with substantial project, studio, or laboratory work. You are expected to work independently and in teams on problems that do not have a single clean answer, and to defend your choices.

Workload and assessment

As a 3-credit course, expect roughly 6–9 hours of work outside scheduled class time each week. Grades are typically based on a mix of a term project or portfolio, quizzes or exams, and participation in critique or seminar discussion, in proportions each instructor sets. Late-work, attendance, and academic-integrity policies are on the section syllabus, which is the authority in any conflict with this page.

Where it fits

Cryptography Applied counts toward the Cybersecurity program and is available as an elective to students in related majors; it may also apply to a minor or a general-education category. See the Cybersecurity course list for the full sequence, and your degree audit for exactly how it applies to your requirements. If you are not sure whether to take it, your academic adviser can tell you where it lands in your plan.

Topics you can expect

Sections vary, but a typical offering of Cryptography Applied spends time on:

• The vocabulary of cybersecurity and the questions the field is trying to answer.
• Core methods, and how practitioners actually apply them.
• Reading, evaluating, and citing evidence, sources, or specifications.
• A recurring problem type worked from a blank page to a defended answer.
• The notation, tools, or software that is standard in the area.
• How the individual pieces fit into a larger system or argument.

The section syllabus sets the actual schedule and the order these are covered in; this list is representative, not a contract.

Materials and cost

Plan on one or two texts and a set of primary readings, some of them library- or instructor-supplied. Where a no-cost open option covers the learning outcomes, the department uses it, so wait for the section syllabus before buying anything. Any figure here is illustrative — UW–Porter Falls is fictional and sets no real prices.

Common questions

Can I enroll without the prerequisite? Not through self-registration. If you have equivalent preparation from transfer work or experience, ask the Cybersecurity department for a registration override before the term begins.

Will it count toward my major or a general-education requirement? It always counts toward Cybersecurity. Whether it satisfies a category in another major, a minor, or general education depends on that program's rules — check your degree audit or ask your adviser.

How heavy is the workload? Budget about 6–9 hours per week beyond scheduled class time. Students who fall behind in the first three weeks tend to stay behind, so pace the early work.
