Explain the basics of encryption and decryption, the key concept, plain text and ciphertext, and common attacks, with examples and references to RSA and Diffie Helminth.
Encrypt each plain letter by shifting with a key, plus three, in a monoalphabetic Caesar cipher. Decrypt by subtracting the key; brute-force can test up to 25 keys.
Explore the Playfair cipher, a polyalphabetic encryption using digraphs and a five-by-five matrix built from a key such as monadic, with rules for digraph handling and row-column substitutions.
Demonstrate the vigna cipher, a polyalphabetic method using a 26 by 26 table and a repeating key to encrypt and decrypt plaintext.
Explain how block ciphers encrypt data in fixed-size blocks and how stream ciphers encrypt byte by byte, with block ciphers suited for large data and stream ciphers for quick exchanges.
Explore the data encryption standard (des) with 64-bit blocks, 56-bit keys, and 16 rounds of 48-bit subkeys, including 2des and 3des variants.
Explore the aes: a 128-bit block cipher with 128-bit keys and 10 rounds, using a 4x4 state matrix and steps like subbytes, shift rows, mix columns, and add round key.
Explore RSA, an asymmetric encryption algorithm using a public key for encryption and a private key for decryption, illustrating key concepts like N, phi(N), e, and d.
Demonstrate the Diffie-Hellman key exchange, showing how Alice and Bob securely derive a shared secret over a public channel using public and private keys for symmetric encryption.
