If you can hack your TCP implementation, you should be able (with a high probability) stego information in a few bits of the TCP checksum by adjusting the packet boundries of the TCP stream. An error correcting code protocol would cover the cases where you couldn't get that *%$# bit set correctly. Please note that this technique would not result in TCP checksum errors. ------------------------------------------------------------------------ Bill Frantz | The CDA means | Periwinkle -- Computer Consulting (408)356-8506 | lost jobs and | 16345 Englewood Ave. frantz@netcom.com | dead teenagers | Los Gatos, CA 95032, USA
