Secure TCP --- providing

3 Goals

The goals of the Secure TCP are shown as follows.

• Provide data integrity for the TCP segment. The data integrity is a security service where right entities can identify data modified by unauthorized entities.
• Provide data confidentiality for TCP segment data. The data confidentiality is a security service where data should be unreadable by unauthorized entities.
• Provide a negotiation service for using various security functions in process/process communication.
• Keep connectivity(interoperability) with a current version of TCP.

Secure TCP does not provide any authentication services by itself. Because several third-party authentication services such as Kerberos are now available, the Secure TCP relies on the authentication services. In this sense, each peer entities in TCP layer has its certificates and the Secure TCP uses it for authentication.
