 CSCI 1515 Applied Cryptography Brown University Spring 2023 Applied Cryptography at Brown University offers a practical take on securing systems. By learning foundational cryptographic algorithms and advanced topics like zero-knowledge proofs and post-quantum cryptography, students gain both theoretical insights and hands-on experience in implementing cryptosystems using C++ and crypto libraries. Label: State-of-art concepts. ### Welcome to Applied Cryptography (CSCI 1515) at Brown!

This course teaches cryptography from a practical perspective and provides hands-on experience in building secure systems.

We first introduce foundational cryptographic algorithms including secret-key and public-key encryption schemes, message authentication codes, digital signatures, and hash functions, from which you will build secure communication and authentication systems.

More advanced topics that are covered include zero-knowledge proofs, secure multi-party computation, fully homomorphic encryption, post-quantum cryptography, and differential privacy. You will learn how these cryptographic techniques can be used to develop more advanced applications such as secure online anonymous voting, secure computation, and private information retrieval.

Besides the high-level design of these cryptosystems, you will also get hands-on experience implementing them using tools from the existing crypto libraries written in C++.    ## Textbooks
