IntroductionPort-based network access control allows a network administrator to

2、 restrict the use of IEEE 802 LAN service access points (ports) to secure communication between authenticated and authorized devices. IEEE Std 802.1X specifies an architecture, functional elements, and protocols that support mutual authentication between the clients of ports attached to the same LAN

3、 and secure communication between the ports. The first edition of IEEE Std 802.1X was published in 2001. The second edition, IEEE Std 802.1X-2004, clarified areas related to mutual authentication and the interface between IEEE 802.1X specified state machine, and those specified by the Extensible Aut

4、hentication Protocol (EAP), and by IEEE Std 802.11 in support of IEEE Std 802.1X. Work on this edition, IEEE Std 802.1X-2010, began as IEEE P802.1af an amendment to specify authenticated key agreement in support of IEEE 802.1AE MAC Security. Part of that work clarified and generalized the relationsh

5、ip between the common architecture specified for port-based network access control, and the functional elements and protocols that support that architecture as specified in IEEE Std 802.1X, other IEEE 802 Standards, and in IETF RFCs. The extent of the changes necessary to IEEE Std 802.1X-2004 made i

6、t appropriate to revise IEEE Std 802.1X as a whole. Further changes updated the standard to reflect best current practice, insisting, for example, upon mutual authentication methods and using such methods in examples. A greater emphasis is placed on the security of systems accessing the network, as

7、well as upon the security of the network accessed, and some prior provisions, such as the controlled directions parameters, have been removed and replaced with a more comprehensive treatment of segregating and limiting connectivity to unauthenticated systems. Every effort has been made to maintain i

8、nteroperability, without prior configuration, with implementations conforming to IEEE Std 802.1X-2004 and IEEE Std 802.1X-2001. However it is anticipated that claims of conformance in respect of some existing implementations will continue to refer to IEEE Std 802.1X-2004. Changes to the functionalit

9、y provided by that prior edition and its documentation include those detailed in the following paragraph. This edition, IEEE Std 802.1X-2010, describes applications of port-based network access that use IEEE 802.1AE MAC Security (MACsec) and/or MKA (MACsec Key Agreement protocol) as well as those pr

10、eviously supported. The specification of the use of EAP for authentication has been updated, enforcing a stricter separation between the port access control protocol (PACP), local to the Supplicant and Authenticator, and the EAP state machines proper. Details of particular EAP methods are no longer

11、interpreted by the PACP machines. The existing EAPOL (EAP over LANs) PDU formats have not been modified, but additional EAPOL PDUs have been added to support MKA and the specification of EAPOL improved. The bibliography, previously Annex F, has been moved to Annex B. The discussions previously in An

12、nex B and Annex C have been updated and integrated into the main body of the standard. The state machine diagram and language conventions, now used by a number of clauses in the standard, have been moved to a new Annex C.
