COSC 62 Applied Cryptography

Cryptography is the fundamental building block for establishing and maintaining trustworthy connections and communications in the Internet; it's the first line of defense for keeping adversaries from spying on credit card numbers being sent to Amazon or on whistleblower reports sent to journalists.  This course will examine what's in this toolkit: symmetric ciphers, public-key cryptography, hash functions, pseudorandomness.  To enable the well-cultured computer scientist to understand how these tools are used in the real world, this course will cover these topics from multiple perspectives: theoretical foundations, use in practical computing, implementation and management challenges, weaknesses and attacks, censorship circumvention, public policy questions, and prospects for the future.


COSC 30, COSC 50. COSC 51 and COSC 55 are recommended.

Degree Requirement Attributes


The Timetable of Class Meetings contains the most up-to-date information about a course. It includes not only the meeting time and instructor, but also its official distributive and/or world culture designation. This information supersedes any information you may see elsewhere, to include what may appear in this ORC/Catalog or on a department/program website. Note that course attributes may change term to term therefore those in effect are those (only) during the term in which you enroll in the course.
