Claim:
1. An operations, administration and maintenance (OAM) security authentication method, comprising the steps of: generating a local random number at a receive end and transmitting the local random number to a transmit end; regarding the local random number as a transmit end random number at the transmit end; determining the local random number at the receive end and the transmit end random number at the transmit end, wherein the local random number is the same as the transmit end random number; transmitting an OAM packet having a random number type-length-value (TLV) field, wherein a value of the random number TLV field is the transmit end random number; and comparing the value of the random number TLV field with the local random number while receiving the OAM packet, wherein if the value of the random number TLV field is the same as the local random number, random number authentication is successful.
