Education: Free Cryptography courses from Prof. Dan Boneh Stanford University

The education platform Coursera has hosted some interesting courses. For example the Stanford University is providing courses about Natural Language Processing, Game Theory, Probabilistic Graphical Models, Cryptography & Design and Analysis of Algorithms.

Coursera is committed to making the best education in the world freely available to any person who seeks it. We envision people throughout the world, in both developed and developing countries, using our platform to get access to world-leading education that has so far been available only to a tiny few. We see them using this education to improve their lives, the lives of their families, and the communities they live in.

Cryptography course by Dan Boneh Professor of Computer Science

Cryptography is an indispensable tool for protecting information in computer systems. This course explains the inner workings of cryptographic primitives and how to correctly use them. Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic.

We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two or more parties generate a shared secret key. We will cover the relevant number theory and discuss public-key encryption, digital signatures, and authentication protocols.

Towards the end of the course we will cover more advanced topics such as zero-knowledge, privacy mechanisms, and other forms of encryption. Throughout the course students will be exposed to many exciting open problems in the field.

Dan Boneh

Professor Boneh's main research area is applied cryptography and network security. His focus is on building security mechanisms that are easy to use and deploy. He has developed new mechanisms for improving web security, file system security, and copyright protection. He contributed to the security and performance of the RSA cryptosystem and contributed to the study of cryptographic watermarking.
