WebDec 12, 2024 · RC4 basically generates a very long key to fit your message. Encryption and decryption is simply xoring with the output of RC4 for that particular position in the key stream. In general, most stream ciphers work that way. The complex part is that the algorithm should generate a very long key that is not susceptible to attack (the ideal being … http://www.crypto-it.net/eng/symmetric/rc4.html

In this paper, we have focused on one such vulnerability of RC4, which makes the cipher prone to Fluhrer, Mantin, and Shamir (FMS) attack and proves the insecurity of RC4 algorithm. To overcome FMS attack, a new variant of RC4 named …
WebNov 5, 2012 · 2. RC4 is a stream cypher, so it uses XOR to encrypt. Running RC4 produces a random looking keystream of bytes. To encrypt you do: plaintext XOR keystream -> cyphertext. To decrypt you do: cyphertext XOR keystream -> plaintext. In both cases the keystream is the same, produced from RC4 using the same key. Share.
