Encryption as a Service using Parallel Computing Frameworks

摘要

In this article I present a study of an implementation named Encryption as a service which is a web service that can be deployed on a various number of devices and that can take advantage of parallelism in order to provide basic functionality of a cryptographic system: encrypt, decrypt and store data. This goal was achieved by implementing symmetric key cryptography algorithm Advanced Encryption Standard (AES) using Open Computing Language (OpenCL) and exposed this functionality through a REST web service .The performance results were obtained by deploying this solution on Windows Azure platform in order to take advantage of 20x CPU computing power m Amazon Web Service platform equipped with 2x Nvidia Tesla K20 GPU and regular home user hardware. This study represents a first step in a broader project which final goal is to provide full support for all encryption algorithms.
