METHOD AND DEVICE FOR CONTROLLING SECURITY CHANNEL IN EPON
摘要
<p>A method and device for controlling security of a communication channel between an OLT and an ONU in a secure channel control system of EPON formed of the OLT and the ONU having a cryptographic module, a key management module and a transmitter/receiver for transmitting/receiving frames, the method comprising the steps of: a) distributing a key between the OLT and the ONU; b) transferring the distributed key to the encryption modules of the OLT and ONU; c) activating a corresponding encryption module using the distributed key at one of the OLT and the ONU which starts a security function activation; d) transmitting an encryption module information message including activation state information of the corresponding encryption module from the side (transmitting side) having the activated encryption module to an opponent side (receiving side); and e) activating an encryption module by checking activation state information of the encryption module at the receiving side.</p>
