In this course you will learn the inner workings of cryptographic systems and how to correctly use them in 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 parties generate a shared secret key.

Ralph Merkle revolutionized cryptography by inventing a protocol that allows two perfect strangers to establish mutual privacy while operating under comprehensive surveillance. His followers:Diffie-Hellman, RSA, ECC are more popular, more convenient, but also more vulnerable to hidden mathematical insight. This video described Merkle's ingenious idea.

A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone. The input data is often called the message, and the hash value is often called the message digest or simply the digest. This video is targeted to blind users.

The Enhanced Sponge Function (ESP) is constructed using two permutation functions. This is in contrast to using only one function as presented in the seminal paper on sponge functions by G. Bertoni et al. The use of only one function carries traces of Merkle-Damgard structure. The shuffling between two permuting functions is performed using a message-dependent pseudo-randomly generated key. Using two pseudo-randomly shuffled functions, providing a non-deterministic data path, increases the uncertainty or entropy in the sponge function output bits. We argue that the proposed construction, without any loss of generality, closely emulates a random oracle more than the original sponge structure using only one function.
