In this example Alice and Bob each generate an ECDH key pair, then exchange public keys. They then use deriveKey() to derive a shared AES key, that they could use to encrypt messages. See the complete code on GitHub. – For example, if p and q are 512-bit numbers, then b is either 1022 or 1023 • Suppose Alice wants to send a message to Bob – She partitions the message into a sequence of b-bit blocks (padding the last block with zeros if necessary) – Encryption and decryption is done on a per block basis – Later we’ll discuss some variations of ...
Figure 1: Alice and Bob use a private-key encryption scheme. Sometimes, in a private key system, an encryption scheme is associated with a message space M and some distribution on M. For example, M may be the set of all strings for a given length. The ciphertext space is the set of all possible plaintext messages m ∈M 4-1 3.1.1 Encryption Encryption is used to communicate securely over an insecure communication channel. Consider Alice communicating with Bob. Any message from Alice to Bob is also received by Eve. To prevent Eve from understanding the message an encryption function E (K enc, m) is used to transform the so called Plaintext, m,
