National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborat

7、e in fields of mutual interest. Other international organizations, governmental and non- governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. IEEE Standards documents ar

The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteer

While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does no

10、t independently evaluate, test, or verify the accuracy of any of the information contained in its standards. The main task of ISO/IEC JTC 1 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publ

25、rol allows a network administrator to 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 clie

26、nts of ports attached to the same LAN 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

27、those specified by the Extensible Authentication 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 cla

28、rified and generalized the relationship 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 nec

29、essary to IEEE Std 802.1X-2004 made it 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

30、of systems accessing the network, as 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. Eve

31、ry effort has been made to maintain interoperability, 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

32、.1X-2004. Changes to the functionality 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 Ag

33、reement protocol) as well as those previously 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

34、particular EAP methods are no longer 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 Anne

35、x B. The discussions previously in Annex 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. Notice to users Laws and regulations User

36、s of these documents should consult all applicable laws and regulations. Compliance with the provisions of this standard does not imply compliance to any applicable regulatory requirements.
