ITU-T X.1158 (11/2014) i Recommendation ITU-T X.1158 Multi-factor authentication mechanisms using a mobile device Summary With the wide use of mobile devices, the number of business transactions carried out through these devices is dramatically
9、increasing. However, there are many weaknesses to single-factor authentication when used in the mobile context requiring strong authentication mechanisms to meet requirements for security and convenience. As such, there is a strong need to develop multi-factor authentication mechanisms that are appl
10、icable to the mobile context. Recommendation ITU-T X.1158 provides multi-factor authentication mechanisms using a mobile device. This Recommendation describes the weaknesses of single-factor authentication mechanisms, the need for multi-factor authentication mechanisms, the various combinations of m
11、ulti-factor authentication mechanisms using a mobile device and the threats for two-factor authentication mechanisms. In addition, security requirements to reduce the threats of single-factor authentication are provided, including potential typical multi-factor authentication mechanisms. This Recomm
12、endation assumes the use of a mobile device with subscriber identity module (SIM) card capability, but should not exclude the use of virtual SIM cards. Specifically, this Recommendation is applicable to all applications using mobile devices. This Recommendation is based on the framework described in

ITU-T X.1158 (11/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agenc
15、y in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view t
16、o standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendation
17、s is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness
18、 to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation i
19、s achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELL
20、ECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whet
21、her asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are ca

27、This Recommendation provides multi-factor authentication mechanisms using a mobile device. It describes the weakness of a single-factor authentication mechanism, identifies the need for multi-factor authentication, and provides various combinations of multi-factor authentication mechanisms using a m
28、obile device. General security requirements to reduce the threats associated with a single-factor authentication mechanism are provided. In addition, typical multi-factor authentication protocols are given. This Recommendation assumes the use of mobile devices with subscriber identity module (SIM) c
29、ard capability, but should not exclude the use of virtual SIM card capability. Specifically, this Recommendation is applicable to all applications using mobile devices. This Recommendation is based on the framework described in ITU-T X.1154. 2 References The following ITU-T Recommendations and other

45、t be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus, this requirement need not be present to claim conformance. Th
46、e keywords “is prohibited from“ indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed. The keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of
47、being recommended. This term is not intended to imply that the vendors implementation must provide the option, and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Reco
