Foreword This Technical Report (TR) has been produced by ETSI Partnership Project oneM2M (oneM2M). ETSI ETSI TR 118 516 V2.0.0 (2016-09) 6oneM2M TR-0016 version 2.0.01 Scope The pr

26、esent document provides technical solutions for oneM2M authorization architecture, authorization procedures and access control policies. The present document also gives evaluations of these proposed technical solutions. ETSI TS 118 103 i.2 only defines a high level authorization architecture that de

27、scribes its major components and general authorization procedure. The objective of the present document is to provide candidate security solutions related to authorization architecture, authorization procedures and access control policies. The present document provides security solutions in the foll

28、owing three aspects: Detailed design of authorization architecture: This part investigates the interfaces among authorization components (e.g. procedures and parameters), how these components could be distributed in different oneM2M entities (i.e. different CSEs), and how to implement Role Based Acc

29、ess Control (RBAC) and token based access control. Supporting user specified access control policies: This part investigates how the oneM2M authorization system could be an extensible system that can support user-defined access control mechanisms and/or access control policy languages. Investigating

30、 existing access control policy languages: This part investigates if some standardized access control policy languages could become oneM2M recommended access control policy description languages. 2 References 2.1 Normative references References are either specific (identified by date of publication

40、a high level overview of a generic authorization architecture. This architecture comprises four subcomponents that are described as follows: Policy Enforcement Point (PEP): - PEP intercepts resource access requests, makes access control decision requests, and enforces access control decisions. The P

41、EP coexists with the entity that needs authorization services. Policy Decision Point (PDP): - PDP interacts with the PRP and PIP to get applicable authorization polices and attributes needed to evaluate authorization policies respectively, and then evaluates access requests using authorization polic

42、ies to render an access control decision. The PDP is located in the Authorization service. Policy Retrieval Point (PRP): - PRP obtains applicable authorization policies according to an access control decision request. These applicable policies should be combined in order to get a finial access contr

43、ol decision. The PRP is located in the Authorization service. ETSI ETSI TR 118 516 V2.0.0 (2016-09) 8oneM2M TR-0016 version 2.0.0 Policy Information Point (PIP): - PIP provides attributes that are needed to evaluate authorization policies, for example the IP address of the requester, creation time o

44、f the resource, current time or location information of the requester. The PIP is located in the Authorization service. The Authorization service may comprise any of the subcomponents: PDP, PRP and/or PIP. This means that the subcomponents PEP, PRP, PDP and PIP could be distributed across different

45、nodes. For example the PEP is located in an ASN/MN and the PDP is located in the IN. The present release 1 does not support separation of PRP and PIP on different CSE from PDP. The generic procedure described below is provided for information and to support further extensions, while clause 7 provide

46、s the details of authorization mechanisms in the current release.

Figure 5.2-1

47、: Authorization Procedure Step 001: Mutual authentication (Pre-requisite). Step 002: Access Requester sends an Access Request to the PEP. Step 003: PEP makes an Access Control Decision Request according to the requesters Access Request, and sends the Access Control Decision Request to the PDP. Step

48、004: PDP sends an Access Control Policy Request that is generated based on the Access Control Decision Request to the PRP. Step 005: PRP finds all access control policies applicable to the access request and sends them back to the PDP. When multiple access control polices are involved, the PRP also

49、provides a policy combination algorithm to combine multiple evaluation results into one finial result. Step 006 PDP sends Attribute Request to the PIP, if any attributes are needed to evaluate these access control policies. Step 007: PIP gets requested attributes and sends them back to the PDP. Step 008: PDP evaluates Access Request using access control policies. When there are multiple applicable access control policies, the PEP needs to calculate a final Access Control Decision using the policy combination algorithm. Step 009: PD
