This paper present new development over the RC4 algorithm (RC4D) via amendment in the first and second parts of the algorithm. In the first part, it increases the use of the key operations to obtain more considerable randomness, while adding one more random variable and use the Xor function...
The implementation of RC4/RC4_128 in SQL Server does not salt the key and this severely weakens the security of data that is encrypted using the RC4/RC4_128 algorithm. In cryptography, an initialization vector (IV) is a fixed size input to a cryptographic algorithm that is typically required...

RC4 Algorithm In the RC4 encryption algorithm, the key stream is completely independent of the plaintext used. An 8 * 8 S-Box (S0 S255), where each of the entries is a permutation of the numbers 0 to 255, and the permutation is a function of the variable length key. There are two...
RC4 cryptography, Stream Cipher, encryption key, file size, data typeAnalysis of the effect of different parameters of the RC4 encryption algorithm where examined. Some experimental work was performed to illustrate the performance of this algorithm based on changing some of these parameters. The ...
