Authentication method of Ethernet passive optical network (EPON) system

Abstract

The invention provides an authentication method of an Ethernet passive optical network (EPON) system. By combining Galois field message authentication code (GMAC), the method realizes authentication process of the EPON system, can support ONU authentication and user authentication simultaneously, and designs a frame structure of the GMAC authentication of the EPON system and protocol process of the ONU authentication and the user authentication. The method can overcome the defect of one-way authentication existing in the EPON system authentication mode under the IEEE802.1X port access control mode, and effectively guarantee the source authenticity and data integrity of the authentication. GMAC has provable security, hash function structure thereof based on a binary Galois field multiplier is suitable for parallel and high-speed implementation of hardware and has increment authentication characteristic, thus leading the method to be capable of meeting the requirements of high-speed and effective identification authentication of the EPON system better and to have good security.

Description

technical field [0001] The present invention relates to an authentication method for optical access network system equipment and user access, in particular to an Ethernet Passive Optical Network (EPON) system authentication method using Galois Domain Message Authentication Code (GMAC), which belongs to information security technology field. Background technique [0002] At present, with the continuous development of network technology and the increasing abundance of broadband services, users' demand for network bandwidth is also increasing. Compared with the digital, highly integrated and intelligent core network, the construction process of the access network is relatively lagging behind, and the access network has become the bottleneck of the broadbandization and further development of the whole network. In recent years, various broadband access technologies have emerged one after another. Among them, the Ethernet passive optical network (EPON) combines the PON technolog...

Problems solved by technology

In practical applications, the IEEE 802.1x protocol has solved the problems caused by traditional authentication methods, but the protocol itself also has some design defects.
