Abstract
Data encryption is essential for protecting data from unauthorized access. The Advanced Encryption Standard (AES), among many encryption algorithms, is the most popular algorithm currently employed to secure static and dynamic data. There are several modes of AES operation. Each of these modes defines a unique way to perform data encryption. XTS mode is the latest mode developed to protect data stored in hard-disk-like sector-based storage devices.
A recent increase in the rate of data breaches has triggered the necessity to encrypt stored data as well. AES encryption, however, is a complex process. As it involves a lot of computations, encrypting huge amount of data would undoubtedly be computationally intensive. Parallel computers have been used mostly in high-performance computation research to solve computationally intensive problems. Parallel systems are currently gaining popularity configured as general purpose multi-core system, even at a desktop level. Several programming models have been developed to assist the writing of parallel programs, and some have already been used to parallelize AES. As a result, AES data encryption has become more efficient and applicable.
The message passing model is a popular parallel communication/synchronization model with an early origin. Message Passing Interface (MPI) is the first standardized, vendor-independent, message passing library interface that establishes a portable, efficient, and flexible standard for message passing during computation. Therefore, this paper describes an implementation of AES using XTS mode in parallel via MPI.
