What is RC4 Keystream Generator?
RC4 Keystream Generator is a Symmetric Crypto IP core from IP Cores, Inc. listed on Semi IP Hub.
Vendor:
IP Cores, Inc.
Category:
Symmetric Crypto
RC4 Keystream Generator
The RC4 core implements the RC4 stream cipher in compliance with the ARC4 specification.
Overview
The RC4 core implements the RC4 stream cipher in compliance with the ARC4 specification. It produces the keystream that consists of 8-bit words using a key with the length up to 256 bits. The design is fully synchronous and available in both source and netlist form. RC4 core is supplied as portable Verilog (VHDL version available) thus allowing customers to carry out an internal code review to ensure its security.
