Research In Motion
The purpose of an encryption algorithm is to provide security of data. If an encryption algorithm cannot be broken easily, then it is said to be secure. The ultimate goal is to protect data against any unauthorized access or theft. In this paper, a comparative study has been done against a family of symmetric key algorithms called the Rivest Cipher algorithms to get a hold on various security goals that the algorithms intends to provide. All the Rivest Cipher algorithms have been described briefly with the basic working principle and other useful details.
