Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identif

40、ying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes

41、of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction WLAN is not a single radio technology: several different technologies fall into the category called WLAN. Existing i

42、ndustry standard is IEEE 802.11b operating at 2.4 GHz ISM band. New entrant for this same band is Bluetooth and technologies such as IEEE 802.11a and ETSI BRAN Hiperlan2 are being developed for the 5 GHz band. Despite the different radio technologies, all these WLAN systems are commonly used for tra

43、nsportation of IP datagrams. The specific WLAN technology used in each wireless IP network is not very visible for the layers above IP. This Technical Specification covers the models and mechanisms under which these technologies can be used to securely interwork with 3GPP networks. ETSI ETSI TS 133

44、234 V13.0.0 (2016-01)73GPP TS 33.234 version 13.0.0 Release 131 Scope The present document specifies the security architecture; trust model and security requirements for the interworking of the 3GPP System and WLAN Access Networks. This specification is not limited to WLAN technologies. It is also v

45、alid for other IP based Access Networks that support the same security capabilities towards the interworking system as WLAN does. These security capabilities are addressed in section 4 of this specification. Specifications of the appropriate mechanisms for user and network authentication, key manage

46、ment, service authorization, confidentiality and integrity protection of user and signalling data are also provided. NOTE: According to the SA plenary decision at SA#64 to stop maintaining the I-WLAN feature from Rel-12 onwards SA3 has agreed that the present document will be maintained only for the

47、 parts where it is referenced from other specifications either for the purposes of backwards compatibility or to allow re-use of generic procedures. 2 References The following documents contain provisions, which, through reference in this text, constitute provisions of the present document. Referenc

48、es are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM docu

49、ment), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 Void 2 Void 3 IETF RFC 3748: “Extensible Authentication Protocol (EAP)“. 4 IETF RFC 4187, January 2006: “Extensible Authentication Protocol Method for 3rd Generation Authentication and Key Agreement (EAP-AKA)“. 5 IETF RFC 4186, January 2006: “Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM)“. 6 IEEE 802.11i-2004: “IEEE Standard for Informat
