WebCryptography studies techniques aimed at securing communication in the presence of adversaries. While encryption is probably the most prominent example of a crypto-graphic problem, modern cryptography is much more than that. In this class, we will learn about pseudorandom number generators, digital signatures, zero-knowledge proofs, WebThis is also referred to as symmetric key encryption. There are two types of symmetric algorithms (or ciphers): stream and block. A block cipher divides the data into blocks (often 64-bit blocks, but newer algorithms sometimes use 128-bit blocks) and encrypts the data one block at a time. Stream ciphers encrypt the data as a stream of bits, one ...
