X.1143 (11/2007) i ITU-T Recommendation X.1143 Security architecture for message security in mobile web services Summary ITU-T Recommendation X.1143 describes the security architecture and scenarios for
8、message security in mobile web services. Security services for messages are the most fundamental security requirements for mobile web services. Although the components for message security such as WS-Security have been standardized, standard architecture and service scenarios for providing message s
9、ecurity for mobile web services have yet to be defined. Since simple object access protocol (SOAP) messages use hypertext transfer protocol (HTTP) ports, they cannot be filtered by firewalls; hence the need to provide a message filtering mechanism based on the message contents in the architecture fo
10、r secure mobile web services as well as to integrate the security policy mechanism suitable for mobile web services message security and the message filtering mechanism into the architecture. Since many mobile terminals do not have sufficient processing power to support the web services protocol sta
11、ck fully, and many back-end application servers are not based on web services, interworking mechanisms and scenarios between mobile web services and legacy non-web services applications should be provided. This Recommendation seeks to establish a guideline for security architecture and security serv
12、ice scenarios for message security in mobile web services satisfying the above-mentioned requirements.

X.1143 (11/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication
14、 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 to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTS
15、A), 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 Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall w
16、ithin 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 to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recom
17、mendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such
18、 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. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommend
19、ation 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, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approva
20、l 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 cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB pat

27、chitecture for message security in mobile web services consisting of various mobile terminals and networks. Interworking mechanisms and service scenarios between applications that support the full web services security protocol stacks and legacy applications that do not support the full web services
28、 security protocol stack. Authentication, integrity and confidentiality mechanisms of the message in the mobile web services environment. Integrated security architecture that utilizes the security policy for message security in the mobile web services environment. Message filtering mechanism based
29、on the message contents for the message security architecture. Reference message security architecture and security service scenarios for mobile web services. The following objectives are not within the scope of this Recommendation: To define a new security policy language or an access control langu
30、age. To define a new transport level security protocol or a message level security protocol. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

40、3.1.17 trust: IETF RFC 2828 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 application service: This is an entity that provides various value-added services to the service requesters. 3.2.2 artifact: A piece of digital information. An artifact may be
41、any size, and may be composed of other artifacts. Examples of artifacts: a message; a URI; an XML document; a PNG image; a bit stream. b-W3C Glossary 3.2.3 discovery: The act of locating a machine-processable description of a web service-related resource that may have been previously unknown and tha
42、t meets certain functional criteria. It involves matching a set of functional and other criteria with a set of resource descriptions. The goal is to find an appropriate web service-related resource. b-W3C Glossary 3.2.4 discovery service: This is an entity that stores interface information for appli
43、cation services and related security policies for access to the application services by clients. Clients can get such information from the discovery service by sending queries that describe the services they want to access. 3.2.5 end point: An association between a binding and a network address, spe
44、cified by a URI, that may be used to communicate with an instance of a service. An end point indicates a specific location for accessing a service using a specific protocol and data format. b-W3C Glossary 3.2.6 gateway: This is a network node that terminates a message on an inbound interface with th
45、e intent of applying some security processing or message conversions to the message, and presenting it to the target service through an outbound interface. 3.2.7 identifier: An identifier is an unambiguous name for a resource. b-W3C Glossary 3.2.8 policy server: This is an entity that manages securi
46、ty policies related to the security processing of messages and access control policies for the messages. 3.2.9 principal: This is an entity whose identity can be authenticated.
