In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. IEEE Standards documents are develo

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

While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not indepe

10、ndently 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. Publication

11、as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibility that implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken wit

All rights reserved.IntroductionPort-based network access control allows a network administrator to restrict the use of IEEE 802 LANservice access points (ports

29、) to secure communication between authenticated and authorized devices. IEEEStd 802.1X specifies an architecture, functional elements, and protocols that support mutual authenticationbetween the clients of ports attached to the same LAN and secure communication between the ports.The first edition of

30、 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 statemachine, and those specified by the Extensible Authentication Protocol (EAP), and by IEEE Std 802.11insupport of IEEE

31、 Std 802.1X.Work on this edition, IEEE Std 802.1X-2010, began as IEEE P802.1afan amendment to specifyauthenticated key agreement in support of IEEE 802.1AE MAC Security. Part of that work clarified andgeneralized the relationship between the common architecture specified for port-based network acces

32、scontrol, and the functional elements and protocols that support that architecture as specified in IEEE Std802.1X, other IEEE 802 Standards, and in IETF RFCs. The extent of the changes necessary to IEEE Std802.1X-2004 made it appropriate to revise IEEE Std 802.1X as a whole. Further changes updated

33、thestandard to reflect best current practice, insisting, for example, upon mutual authentication methods andusing such methods in examples. A greater emphasis is placed on the security of systems accessing thenetwork, as well as upon the security of the network accessed, and some prior provisions, s

34、uch as thecontrolled directions parameters, have been removed and replaced with a more comprehensive treatmentof segregating and limiting connectivity to unauthenticated systems.Every effort has been made to maintain interoperability, without prior configuration, with implementationsconforming to IE

35、EE Std 802.1X-2004 and IEEE Std 802.1X-2001. However it is anticipated that claims ofconformance in respect of some existing implementations will continue to refer to IEEE Std 802.1X-2004.Changes to the functionality provided by that prior edition and its documentation include those detailed inthe f

36、ollowing paragraph.This edition, IEEE Std 802.1X-2010, describes applications of port-based network access that use IEEE802.1AE MAC Security (MACsec) and/or MKA (MACsec Key Agreement protocol) as well as thosepreviously supported. The specification of the use of EAP for authentication has been updat

37、ed, enforcing astricter separation between the port access control protocol (PACP), local to the Supplicant andAuthenticator, and the EAP state machines proper. Details of particular EAP methods are no longerinterpreted by the PACP machines. The existing EAPOL (EAP over LANs) PDU formats have not be

38、enmodified, but additional EAPOL PDUs have been added to support MKA and the specification of EAPOLimproved. The bibliography, previously Annex F, has been moved to Annex B. The discussions previouslyin Annex B and Annex C have been updated and integrated into the main body of the standard. The stat

39、emachine diagram and language conventions, now used by a number of clauses in the standard, have beenmoved to a new Annex C.Notice to usersLaws and regulationsUsers of these documents should consult all applicable laws and regulations.
