ciphertext associated with a given key
11Format-preserving encryption — In cryptography, format preserving encryption (FPE) refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of format varies. Typically only finite domains are discussed …
12Plaintext-aware encryption — Plaintext awareness is a notion of security for public key encryption. A cryptosystem is plaintext aware if it is difficult for any efficient algorithm to come up with a valid ciphertext without being aware of the corresponding plaintext.From a… …

17The Magic Words are Squeamish Ossifrage — The text The Magic Words are Squeamish Ossifrage was the solution to a challenge ciphertext posed by the inventors of the RSA cipher in 1977. The problem appeared in Martin Gardner s Mathematical Games column in Scientific American . It was… …
18Paillier cryptosystem — The Paillier cryptosystem, named after and invented by Pascal Paillier in 1999, is a probabilistic asymmetric algorithm for public key cryptography. The problem of computing n th residue classes is believed to be computationally difficult. This… …
19A5/1 — is a stream cipher used to provide over the air communication privacy in the GSM cellular telephone standard. It was initially kept secret, but became public knowledge through leaks and reverse engineering. A number of serious weaknesses in the… …
20Keystroke logging — (often called keylogging) is a method of capturing and recording user keystrokes. The technique and name came from before the era of the graphical user interface; loggers nowadays would expect to capture mouse operations too. Keylogging can be… …
