Cryptography is one of the key elements in providing security for modern e-commerce systems. It is well known that software-based encryption has built-in security weaknesses due to storing and managing digital certificates/keys in a high-risk environment such as a local hard disk or software. This makes embedded hardware encryption a superior solution. However, most existing embedded hardware encryption modules need additional dedicated software in order to implement a secure e-commerce application, which increases cost as well as adds complexity. In this paper, a new embedded hardware DSP (Digital Signal Processor) encryption module, using the RSA (Rivest, Shamir, and Adleman) algorithm, is developed for secure e-commerce transactions from the client side.
