New design strategy of dynamic security implementation

Motivated by the lack of efficiency in existing network security protocols (TKIP, Kerberos, EAPOL-RADIUS, etc.), we introduce our own model, synchronous dynamic encryption system (SDES), in order to compensate for their drawbacks. Our analysis of standard modern security mechanisms shows that these solely focus on security, sacrificing speed and channel bandwidth. The main theme of our research is to achieve solid communication security without trading off the efficiency. Unique to our SDES system is the involvement of the communication history (plains and ciphers) and a non-reversible hash function in the key management process. Moreover, the security strength of the slow and complex traditional encryption functions is distributed over the SDES key management, yielding a much faster (yet secure) XOR encryption function. Preliminary experimentation with the SDES showed very promising system performance and security enhancement, over existing peers.
