26、otocol defines how to securely associate an IP-connected media device (such as a hybrid radio, set top box or Smart TV) with the online account of a user of a set of web services delivered to that device. Introduction The present document specifies version 1.0 of the Cross Platform Authentication (C

27、PA) protocol. The CPA protocol is specifically designed for devices with limited input and display capabilities that are not addressed by existing standards and to cater for companies that share a back-end authorization provider for managing identities but implement services separately. The CPA prot

28、ocol defines a clear separation of responsibilities between the service provider and the authorization provider. This enables the protocol to be applied in a variety of business configurations typical of the broadcast industry. For example, the CPA protocol can be used in the following scenarios: th

29、e service provider and the authorization provider are both managed by the same company; an umbrella company manages the authorization provider (so centralizing identity management) but keeps its service providers separate from one another; service providers from different companies use the same cent

30、ral authorization provider managed by a separate company (e.g. a national federated identity service). ETSI ETSI TS 103 407 V1.1.1 (2016-04)7 1 Scope 1.1 General The protocol described in the present document is intended for devices with limited input capabilities, such as hybrid radios, IP-connecte

31、d set top boxes and Smart TVs, that can communicate with web services over HTTPS. The protocol specifies two APIs: the API between a client device and an authorization provider by which a client obtains a bearer token; the API between a service provider and an authorization provider by which a servi

32、ce provider verifies an access token. The present document gives an overview of the protocol (clause 4), covering the core concepts (clause 5) and roles (clause 6) used in CPA and how the device flow works (clause 7). The CPA APIs are specified in the present document in clauses 8, Client/Authorizat

33、ion Provider API and clause 9, Service Provider/Authorization Provider API. An informative annex A describes how service providers can tell clients that the option to authenticate using the CPA protocol is available, and how the bearer token obtained via CPA should be used to access protected resour

34、ces. Although this clause is not normative, it is strongly recommended these conventions are followed where possible to maximize interoperability. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-s

While CPA can be used more generally, the focus of the present document is on IP-connected media devices with limited input and display. When such a device cannot run a fully capable HTTP User Agent such as a browser, the user needs access to another device which can run such software to complete the authorization. In the typical CPA device flow described below, the application-specific steps are prefixed with (
