Semantic security: History, Public-key cryptography & Symmetric-key cryptography

In cryptography, a semantically secure cryptosystem is one where only negligible information about the plaintext can be feasibly extracted from the ciphertext. Specifically, any probabilistic, polynomial-time algorithm (PPTA) that is given the ciphertext of a certain message m {\displaystyle m} (taken from any distribution of messages), and the message's…
