X.1122 (04/2004) i ITU-T Recommendation X.1122 Guideline for implementing secure mobile systems based on PKI Summary Although public-key infrastructure (PKI) technology is very useful security technology to realize many security functions (encipherment, digital signa

8、ture, data integrity, and so on) in the mobile end-to-end data communications, the PKI technology should be adapted for mobile end-to-end data communication. However, the method to construct and manage secure mobile systems based on PKI technology has not been established yet. This Recommendation pr

9、ovides guidelines for constructing secure mobile systems based on PKI technology. Source ITU-T Recommendation X.1122 was approved on 29 April 2004 by ITU-T Study Group 17 (2001-2004) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. X.1122 (04/2004) FOREWORD The International Telecommunica

10、tion Union (ITU) is the United Nations specialized agency in the field of telecommunications. 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 v

11、iew to 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 Recommend

12、ations 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 concis

13、eness 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 Recommendatio

14、n is 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. INT

15、ELLECTUAL PROPERTY RIGHTS ITU 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,

16、whether 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, implementors ar

17、e cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2004 All rights reserved.

The range of applications of this Recommendation shall be as follows: Its subject shall be the control of certi

24、ficates in the mobile end-to-end data communication in general.

38、ories to which PKI technologies belong PKI technology is the security technology that is applied to the relation between a mobile terminal and an application server in the general model of mobile end-to-end data communication between a mobile user and an ASP, or to the relation between a mobile term

39、inal and a mobile security gateway, and between a mobile security gateway and a server in the gateway model of mobile end-to-end data communication between a mobile user and an ASP. PKI technology is a security technology that is used to realize the following security functions: 1) Encipherment; 2)

40、Key Exchange; 3) Digital Signature; 4) Access Control; 5) Data Integrity; 6) Authentication Exchange; 7) Notarization. 4 ITU-T Rec.

42、hough PKI technology is often used in an open network to realize the above-mentioned security functions, due to characteristics of mobile end-to-end data communication, especially low processing power and small memory size, some adaptations of PKI technologies for mobile end-to-end data communicatio

43、n are needed. 6 Models of secure mobile systems based on PKI As for other secure mobile systems, models of secure mobile systems based on PKI are classified as follows: a general model of secure mobile systems based on PKI for communication between a mobile user and an ASP, and a gateway model of se

44、cure mobile systems based on PKI for communication between a mobile user and an ASP. However, for the purpose of PKI operations (for example, life cycle management of certificate), some entities (CA, RA, VA, Repository and so on) are added into the models. 6.1 General model of secure mobile systems

45、based on PKI A general model of secure mobile systems based on PKI for communication between a mobile user and an ASP is shown in Figure 1. ITU-T Rec.

46、 CAASPsVAFigure 1/X.1122 General model of secure mobile systems based on PKI This model contains additional entities to that of the general model of mobile end-to-end data communication between a mobile user and an ASP; i.e., the mobile users side CA (contains RA and repository), mobile users VA, AS

47、Ps side CA and ASPs VA. Mobile users CA The mobile users side CA issues and manages the mobile users certificate or the mobile terminals certificate. This contains RA that is responsible for the identification and authentication of the mobile user and the repository that stores the mobile users cert

48、ificate and CRL. Mobile users VA The mobile users VA provides an online service of verification of validity of certificate received by mobile user to mobile user. ASPs side CA An ASPs side CA issues and manages the ASPs certificate or application servers certificate. This also contains RA that is re

49、sponsible for the identification and authentication of the ASP and the repository that stores the ASPs certificate and CRL. ASPs VA The ASPs VA provides an online service of verification of validity of certificate received by the ASP. 6.2 Gateway model of secure mobile systems based on PKI A gateway model of secure mobile systems, based on PKI for communication between mobile user and an ASP is shown in Figure 2. 6 ITU-T Rec.
