Data encryption features for computer hardware and software profitability: I/O ports, expansion slots, algorithms, cyphers and security

Research output: Contribution to journalArticle


The use of encryption to protect sensitive data has existed in one form or another throughout history. Today, the massive amounts of data transmitted regularly make it more important than ever to ensure the integrity of important information during transmission by means of data encryption. The selection of appropriate features for inclusion in data encryption products can be very frustrating for both hardware and software manufacturers, as well as for end-users. This study describes an interactive microcomputer-based feature selection system. The feature price contribution margin measures to what degree a specific feature meets end-user needs. It compares the outcome of integrating and bundling a feature into a product with marketing this feature as a separate "add-on" product line.
