When using the Internet, users retrieve or share information. Depending on the application, purpose, and implementation methods, the need to provide data confidentiality, integrity, and authenticity emerges. To ensure these requirements are fulfilled and that only authorized parties have access to the data, the information transmitted over the Internet is obfuscated.
