To any person engaged in highly sensitive information exchanges, the issue of secure transmissions is a top priority. This book shows readers how to protect themselves and their electronic information in order to enjoy the benefits of worry-free communication technology and digital commerce. It opens with an introduction to the concepts of modern encryption: secret-key encryption, public key encryption, digital signatures, and user authentication mechanisms. It moves into why encryption is necessary, how it can be used to protect information at the individual level, and how cryptographic technologies are implemented in both software and hardware. It also shows how to set up a personal encryption system, and how to use it to protect yourself while browsing the Web, sending and receiving e-mail, or using any Internet application.

On the Internet, everyone can hear you scream...
Ever eavesdrop on a conversation in a restaurant? The Internet is a virtual restaurant with millions of tables and perfect acoustics--and if you you expect any privacy, you're dreaming. I wrote this book to help real people understand how encryption and digital signatures can be used to protect their personal and business data--online and off.
Read this book if you want to learn how encryption and digital signatures work--and how you can use them to encrypt your e-mail and data files. Also included are sections on Web security, cookies, Web anonymizers, and plenty of hands-on guidance to using the software you've already got to protect yourself.
