“…However, although it is not considered very secure [ 8 ], RC4 continues to motivate research nowadays [ 8 , 9 , 10 ]. Furthermore, this cipher is a good option to measure the effectiveness of methods that analyze weaknesses in stream ciphers related to those already known in RC4 [ 11 , 12 , 13 , 14 ], or to check the performance of hardware or software schemes that make use of cryptography [ 15 , 16 , 17 ].…”

This paper presents a criterion, based on information theory, to measure the amount of average information provided by the sequences of outputs of the RC4 on the internal state. The test statistic used is the sum of the maximum plausible estimates of the entropies H(jt|zt), corresponding to the probability distributions P(jt|zt) of the sequences of random variables (jt)t∈T and (zt)t∈T, independent, but not identically distributed, where zt are the known values of the outputs, while jt is one of the unknown elements of the internal state of the RC4. It is experimentally demonstrated that the test statistic allows for determining the most vulnerable RC4 outputs, and it is proposed to be used as a vulnerability metric for each RC4 output sequence concerning the iterative probabilistic attack.

“…However, although it is not considered very secure [36], RC4 is still one of the most widely used stream ciphers [37], and continues to motivate research nowadays [36][37][38]. Furthermore, this cipher is a good option to measure the effectiveness of methods that analyze weaknesses in stream ciphers related to those already known in RC4 [22,[24][25][26], or to check the performance of hardware or software schemes that make use of cryptography [39][40][41].…”

The bit independence criterion was proposed to evaluate the security of the S-boxes used in block ciphers. This paper proposes an algorithm that extends this criterion to evaluate the degree of independence between the bits of inputs and outputs of the stream ciphers. The effectiveness of the algorithm is experimentally confirmed in two scenarios: random outputs independent of the input, in which it does not detect dependence, and in the RC4 ciphers, where it detects significant dependencies related to some known weaknesses. The complexity of the algorithm is estimated based on the number of inputs l, and the dimensions, n and m, of the inputs and outputs, respectively.

“…The word cryptography means cipher writing. Cryptography is a way of protecting information at rest state and communication state through the uses of encryption, and only decryption key holder can access the information [7]. It has three process; key generation, encryption, and decryption process.…”

Cloud computing is on-demand access to computer system resources through the internet. Among various services provided by the cloud, most prominent is the cloud for storage. Because cloud services are present over the internet, which invites some trust issues among customers regarding integrity and confidentiality about the data, it is the challenge for the cloud to assure customers that their data is safe and can be retrieved whenever they want. This paper presents a survey of various schemes that applied to achieve confidentiality and integrity in the cloud system. Generally, encryption/decryption schemes and hashing techniques are used to obtain privacy and integrity, respectively. This paper also gives a comparative study of some encryption/decryption schemes as well as some hashing schemes.
