ENCRYPTION USING RC-4
[attachment=26395]
RC-4 OVERVIEW
Rc4 is an Symmetric key Encryption algorithm. It was invented by Ron Rivest.
RC4 is a stream cipher, which actually means that we generate streams of byte one for each byte of the text we want to encrypt. It can be implement both in software as well as hardware.
The encryption process is divided into two main parts.
The key scheduling algorithm (KSA)
The pseudo random generation Algorithm (PRGA).
ADVANTAGES OF RC-4
RC-4 algorithm is widely deployed today because of its
simplicity and speed of conversion.
Encryption is about 10 times faster than DES.
