Software Based Encryption for Local Area Networks
Abstract The widespread use of local area networks within commercial organisations has raised concerns about the confidentiality of information carried by such networks. The provision of data privacy ideally requires dedicated encryption chips used in conjunction with access control and authorisation mechanisms. The availability of low-cost encryption chips is several years off, but how can data be protected in the short term?. This paper describes an experimental project to investigate and prove the feasibility of low-cost software-based encryption suitable for local area networks.
