Abstract

Data encryption can be implemented either by hardware or by software. It is generally accepted that software encryption is flexible, more cost-effective as well as easier to develop and to maintain, but it is significantly less secure and slower than its hardware equivalent. Since either hardware-based security or software-based security has its own pros and cons, a company needs to consider many factors like budget, performance, security, governing regulations, etc, to decide on choosing either hardware or software based security implementations. No matter which solution a company chose, they should be consciously aware of the “good”, “bad” and “ugly” of the solution they pick! Thus, to choose or not to choose hardware-based security is a big decision for every company to make regarding protecting their highly important sensitive information from unauthorized access. The focus of this article is on the “good”, “bad” and the “ugly” of hardware-based security.

Introduction

Data encryption has been used extensively by the governments, financial institutions, and other business to protect their highly important sensitive information from unauthorized access. There are basically two types of encryption methods that are available, namely, hardware-based and software-based encryption.

Generally speaking, hardware based encryption is considered to be safer/more secure, faster, and better assured than its software equivalent by many computer experts. However, it is also more costly, less flexible, and not easy to update or upgrade compared to its software equivalent.

This article will discuss the “good”, “bad” and the “ugly” of hardware-based security…
