Abstract
A system is provided for use in a network providing security to ensure the prevention of unauthorized receipt of data. The system utilizes a jamming sequence to prevent unauthorized ports from receiving certain data. Repeaters utilized in the network are provided with the capability to detect a particular data sequence to provide the improved features.
Claims6
A system for providing security for a network that includes a plurality of ports for transmitting and receiving data, the data including a bit that indicates the start of a data stream and a bit corresponding to each port that is to receive the data the system comprising;
- a plurality of disrupt circuits means coupled to the plurality of ports, there being one disrupt circuit means for each port, each of the disrupt means being coupled in a serial fashion;
- a detect circuit means coupled between a first disrupt circuit means and a last disrupt circuit means to detect when the start bit has reached to last disrupt circuit means;
- and
- means for providing a jam sequence of data that will block a data bitstream from reaching a particular port responsive to the detect circuit means.
