METHOD FOR PROVIDING MAC PROTOCOL FOR DATA COMMUNICATION SECURITY IN WIRELESS NETWORK COMMUNICATION

摘要

The present invention is a wireless network in the MAC service method protocol for data communication security in a communication system, the encrypted key for the time stamp (time stamp), and encryption for time synchronization (sync) in data transmission node Dude de ( key seed) generating a value, this process generates a RTS (request to send) the message data frame containing a data field area to transmit to the data receiving node, and the RTS message data frame the time in the data reception node receives the after demodulating the stamping and key Dude dE value, this basis generates a time stamp and key Dude dE value by including it in the data field area of the CTS (clear to send) the message data frame and transmitting the RTS message, the data frame which one and transmitting to the node, and the process by the time stamp values received from the data transmitting node receives the CTS message, the data frame and performs a change in the duration of the channel characterized in that it comprises. ; frequency hopping, channel negotiation, the time slot
