protocol for securing IP communications by authentication and encryption of each IP packet of a communication session. IPSec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiating cryptography keys which is to be used during the session. IPSec is an end to end security scheme operating in the Layer of Internet of the IP suite. It can be used in protecting data flows between a pair of hosts‚ between a pair of security gateways‚ or between

The advantage of steganography over cryptography alone is that steganographic message does not attract attention to communicating parties. An apparent encrypted message‚ no matter how unbreakable it is‚ can arouse suspicion and may in itself be incriminating. If suspicion is raised‚ then the goal of steganography is defeated. Since there is always a possibility that secret communication will be uncovered‚ steganography is often used together with cryptography. A steganographic message (the plaintext)
