This course will build on the fundamentals of basic cryptographic knowledge and cover more advanced tools, real applications, and best practices. Topics include formal definition of indistinguishability security for pseudo-randomness, encryption, and authentication. Techniques for constructing concrete hash functions including sponge, Feistel-base, and Merkle-Damgrad extensions. Application to message authentication, including key concepts and various schemes. Password-less authentication mechanisms. Asymmetric primitives. Modern applications include practical authenticated encryption standards, elliptic curve cryptography, blockchains, zero knowledge protocols, cryptocurrencies, secret sharing and more
