"WebThrough cryptanalysis, there is no strong correlation between the key and the plain image, which leads to the collapse of cryptosystem. Based on this, two methods of chosen-plaintext attacks are proposed in this paper. The two methods require 3 pairs and 258 pairs of plain and cipher images, respectively, to break the original encryption system. " - Cryptanalysis and attacks

WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit.

WebCryptanalysis attack where the attacker is assumed to have access only to a set of ciphertexts. This is where the attacker has access to the ciphertext, and his goal is to recover the encryption key from it. This attack requires a hacker to obtain encrypted messages that have been encrypted using the same encryption algorithm.
