Communications security on the Internet

The explosive growth of the Internet and its advance into practically all areas of daily life mean that related security aspects are increasingly gaining in importance:

• Communications security, in other words data authenticity, data integrity, data confidentiality, etc.

• Reliability, in other words general availability of the systems involved

• Protection against viruses, worms, Trojan Horses, backdoors, etc.

The focus of TLS and thus of this chapter consists of aspects relating to communications security.
