Abstract:
The present invention provides an operations, administration and maintenance (OAM) security authentication method and OAM packet transmitting/receiving devices. An OAM packet is authenticated by utilizing a random number and an authentication code. A threshold for the number of failed authentication is determined. If the number of failed authentication is greater than the threshold, the random number will be updated. According to the present invention, OAM packets constructed by malicious users or tampered with may be detected to increase security of OAM packets and avoid a denial-of-service (DOS) attack.
