Secure TCP-IP Network Algorithm (original) (raw)

In recent days network plays a key role in most modern applications. Especially through the services provided by Internet. Our paper presents simple rigid network security system. The system adopt the Transmission Control Protocol (TCP) as main protocol. TCP protocol is reliable connection protocol, but the main security method use are simple. And there is a need to improve its facilities. Blowfish is simple fast secure algorithm. By adopting the Blowfish method in specific position in the hierarchy of the TCP-IP layer a new secure model will be result. Also the system has the ability to be used with any recent application by follow simple steps.
