In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher. ... First, the basic RC4 algorithm is performed using S1 and j1, but in the last step, S1[i]+S1[j1] is looked up in S2. See more In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher. While it is remarkable for its simplicity and speed in software, multiple vulnerabilities have been … See more RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). RC4 was initially a trade secret, but in September 1994, a … See more Unlike a modern stream cipher (such as those in eSTREAM), RC4 does not take a separate nonce alongside the key. This means that if a single long-term key is to be used to securely … See more • WEP • TKIP (default algorithm for WPA, but can be configured to use AES-CCMP instead of RC4) • BitTorrent protocol encryption See more RC4 generates a pseudorandom stream of bits (a keystream). As with any stream cipher, these can be used for encryption by combining it with the plaintext using bitwise exclusive or; decryption is performed the same way (since exclusive or with given data is … See more As mentioned above, the most important weakness of RC4 comes from the insufficient key schedule; the first bytes of output reveal information about the key. This can be … See more • TEA, Block TEA also known as eXtended TEA and Corrected Block TEA – A family of block ciphers that, like RC4, are designed to be very simple to … See more WebAug 9, 2024 · Asymmetric or public key cryptography is the form of encryption that involves using public and private keys for encryption and ...
