WebThe ARC4-IP-44 (EIP-44) is IP for accelerating the ARC4 stream cipher algorithm (used for legacy SSL & IPsec) up to 5 Gbps @ 600MHz. Designed for fast integration, low gate count and full transforms, the ARC4-IP-44 accelerator provides a reliable and cost-effective embedded IP solution that is easy to integrate into high-speed crypto pipelines.

ARC4 (Alleged Rivest Cipher 4) - CONFIG_CRYPTO_ARC4 - arc4.ko ...
WebARC4 (key) [source] ARC4 (Alleged RC4) is a stream cipher with serious weaknesses in its initial stream output. Its use is strongly discouraged. ARC4 does not use mode constructions. Parameters: key (bytes-like) – The secret key. This must be kept secret. Either 40, 56, 64, 80, 128, 192, or 256 bits in length. WebApr 14, 2024 · ARC4, ot RC4is a stream cipher developed by Ron Rivest in 1987 for RSA Data Security Inc. The cipher uses a 40-bit to 2048-bit key, and no initialization vector. … 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 discovered in RC4, rendering it insecure. It is especially vulnerable when the beginning of the … 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). 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 … See more • WEP • TKIP (default algorithm for WPA, but can be configured to use AES-CCMP instead of RC4) • BitTorrent protocol encryption • Microsoft Office XP (insecure implementation since nonce remains unchanged when documents get modified ) 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 … See more As mentioned above, the most important weakness of RC4 comes from the insufficient key schedule; the first bytes of output reveal … 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 • Paul, Goutam; Subhamoy Maitra (2011).
