Encryption

The coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.

encryption

The manipulation of data to prevent accurate interpretation by all but those for whom the data is intended. Financial institutions use encryption to increase the security of data transmitted via the Internet.

Block ciphers like RC5, RC6 use DDR instructions which make them vulnerable to differential attacks.
There are basically two ways to make a stronger cipher: the stream cipher, where the encryption rule is developed depending on a plaintext symbol's position in the stream of plaintext symbols, and the block cipher, which encrypts several plaintext symbols at once in a block [1].
The proposed approach uses stream cipher based RC4 algorithm for data burst confidentiality.
