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 collaborate in fields of mutual in

7、terest. 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 are developed within the IE

8、EE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied vie

9、wpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate,

10、 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 as an Internation

11、al 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 with respect to the

12、existence or validity of any patent rights in connection therewith. ISO/IEEE is not responsible for identifying essential patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any lic

13、ensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration Form, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validit

14、y of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from ISO or the IEEE Standards Association. ISO/IEC/IEEE 8802-1AE was prepared by the LAN/MAN Standards Committee of the IEEE Computer Society (as IEEE Std 8

15、02.1AE-2006).

24、1AE and other IEEE 802 standardsAnother IEEE standard, IEEE Std 802.1X-2004, specifies Port-based Network Access Control, andprovides a means of authenticating and authorizing devices attached to a LAN. Use of this standard inconjunction with architecture and protocols of IEEE Std 802.1X-2004 extend

25、s the applicability of the latterto publicly accessible LAN/MAN media for which security has not already been defined. A proposedamendment, IEEE P802.1af, to IEEE Std 802.1X-2004 is being developed to specify the additionalprotocols and interfaces necessary.This standard is not intended for use with

26、 IEEE Std 802.11, Wireless LAN Medium Access Control. Anamendment to that standard, IEEE Std 802.11i-2004, also makes use of IEEE Std 802.1X-2004, thusfacilitating the use of a common authentication and authorization framework for LAN media to which thisstandard applies and for Wireless LANs.A previ

44、edia Access Control (MAC) Security1. Overview1.1 IntroductionIEEE 802Local Area Networks (LANs) are often deployed in networks that support mission-criticalapplications. These include corporate networks of considerable extent, and public networks that supportmany customers with different economic in

45、terests. The protocols that configure, manage, and regulateaccess to these networks typically run over the networks themselves. Preventing disruption and data lossarising from transmission and reception by unauthorized parties is highly desirable, since it is not practicalto secure the entire networ

46、k against physical access by determined attackers.MAC Security (MACsec), as defined by this standard, allows authorized systems that attach to andinterconnect LANs in a network to maintain confidentiality of transmitted data and to take measures againstframes transmitted or modified by unauthorized

47、devices.MACsec facilitatesa) Maintenance of correct network connectivity and servicesb) Isolation of denial of service attacksc) Localization of any source of network communication to the LAN of origind) The construction of public networks, offering service to unrelated or possibly mutually suspicio

48、uscustomers, using shared LAN infrastructurese) Secure communication between organizations, using a LAN for transmissionf) Incremental and non-disruptive deployment, protecting the most vulnerable network components.To deliver these benefits, MACsec has to be used in conjunction with appropriate pol

49、icies for higher-levelprotocol operation in networked systems, an authentication and authorization framework, and networkmanagement. IEEE P802.1afB21provides authentication and cryptographic key distribution.MACsec protects communication between trusted components of the network infrastructure, thus protectingthe network operation. MACsec cannot protect against attacks facilitated by the trusted components1The numbers in brackets correspond to those of the bibliography in Annex B.g44g54g50g18g44g40g38g1
