Abstract Analysis of the effect of different parameters of the RC4 encryption algorithm where
examined. Some experimental work was performed to illustrate the performance of this …

The RC5 encryption algorithm was designed by Professor Ronald Rivest of MIT and first
published in December 1994 17. Since its publication, RC5 has attracted the attention of …

File security is critical in maintaining the confidentiality of the information, especially
sensitive information that should only be known by authorized persons only. If the data is not …

This paper discusses several important algorithms used for the encryption and decryption of
data in all fields, to make a comparative study for most important algorithms in terms of …

Cloud computing has to become the next-generation architecture of IT Enterprise. Clouds
are massively complex systems. They can be reduced to simple primitives, that are …

This paper analyzes the security of the RC5 encryption algorithm against differential and
linear cryptanalysis. RC5 is a new block cipher recently designed by Ron Rivest. It has a …

This paper investigates the encryption efficiency of RC6 block cipher application to digital
images, introducing a mathematical measure for encryption efficiency, which we will call the …

This paper describes a timing attack on the RC5 block encryption algorithm. The analysis is
motivated by the possibility that some implementations of RC5 could result in the data …

In this report, we point out a serious security flaw in Microsoft Word and Excel. The stream
cipher RC4 with key length up to 128 bits is used in Microsoft Word and Excel to protect the …

Now days, Data security is very challenging issue that touches many areas including
computers and communication. Recently, we came across many attacks on cyber security …
