Lecture: 3 hours
Laboratory: 1 hour
Introduction to the theory and practice of cryptographic techniques used in computer security. Encryption (secret-key and public-key), message authentication, digital signatures, entity authentication, key distribution, and other cryptographic protocols. The social context of cryptography.
Prerequisites: (ECS 020 or MAT 108); (ECS 010 or ECS 032A or ECS 030 or ECS 036A)

Summary of course contents
Topics to include most or all of the following:
Science & Engineering
Scientific Literacy: The course treats not only the technical aspects of cryptography (modeling security questions, devising protocols, analyzing methods, and drawing connections to mathematics), but also the societal context in which cryptography is developed and used. Issues of public policy are relevant to many of the topics discussed in this class (eg, the role of intellectual property in and surrounding cryptography), and discussion of these issues is integrated with more purely technical material. Students are assessed based on their homework, exams, and project, these encompassing both a technical and situational understanding of the area.
Quantitative Literacy: Cryptography is a quantitative and analytic subject, one in which theorems make quantitative assertions about the worth of our artifacts, but where, nevertheless, these claims are routinely misunderstood or ascribed meaning other than that which is formally claimed. Thus understanding the real-world interpretation of highly technical, analytic claims—particularly the meaning of provable-security assertions—is a key aspect of this course. Homework develops these skills, while homework and exams permit assessment of whether students can bridge the formal and interpretive divide.
Overlap: There is a small amount of overlap with course 153, Computer Security, which briefly discusses methods for shared-key and public-key encryption. ECS 127 provides a much broader and deeper description of contemporary cryptography.
