A known plaintext attack on the ISAAC keystream generator
ISAAC Keystream generator Cryptanalysis
2009/4/16
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 secu...

Known-Plaintext Attack Permutation Video Encryption Algorithm
2009/3/20
One of the approaches to deliver real-time video encryption is to apply permutations to the
bytes within a frame of a fully encoded MPEG stream as presented in [2]. We demonstrate that
this particul...
