Known-Plaintext Attack and Ciphertext-Only Attack for Encrypted Single-Pixel Imaging

Known Plaintext Attack

In cryptography, the known plaintext attack, or KPA, is an attack based on having samples of both the plaintext and corresponding encrypted or ciphertext for that information available. This information is used to conduct an analysis of the data in order to determine the secret key used to encrypt and decrypt the information. Historical ciphers are very susceptible to the attack, while modern-d...

Known-Plaintext-Only Attack on RSA-CRT with Montgomery Multiplication

The paper describes a new attack on RSA–CRT employing Montgomery exponentiation. Given the amount of so-called final subtractions during the exponentiation of a known message (not chosen, just known), it creates an instance of the well known Hidden Number Problem (HNP, [2]). Solving the problem reveals the factorization of RSA modulus, i.e. breaks the scheme. The main advantage of the approach ...

Known Plaintext Correlation Attack against RC5

A known plaintext attack on the ISAAC keystream generator

Stream ciphers are often used in applications where high speed and low delay are a requirement. The ISAAC keystream generator is a fast software-oriented encryption algorithm. In this papers the security of the ISAAC keystream generator is investigated. Cryptanalytic algorithm is developed for a known plaintext attack where only a small segment of plaintext is assumed to be known.

A Known Plaintext Attack on the PKZIP Stream

Abs t r ac t . The PKZIP program is one of the more widely used archive/ compression programs on personM, computers. It also has many compatible variants on other computers~ and is used by most BBS's and ftp sites to compress their archives. PKZIP provides a stream cipher which allows users to scramble files with variable length keys (passwords). In this paper we describe a known pla.intext att...
