Introduction The present document presents a security threat analysis of RRS networks and devices for a set of specific use cases and operational scenarios defined in ETSI TC RRS. It is recommended to consider i.1,

44、 i.2, i.3, i.5, i.6, i.7, i.8 and i.18 for further information on the framework related to the solutions in the present document. ETSI ETSI TR 103 087 V1.2.1 (2017-11) 9 1 Scope The present document provides an analysis of the risk of security attacks on the operation of reconfigurable radio systems

45、. It identifies which security threats can disrupt RRS networks and devices or can induce negative impacts on other radio communication services operating in the same radio spectrum. The present document also identifies stakeholder and assets, which can be potentially impacted by the security threat

46、s. The present document extends the set of use cases addressed over those covered by ETSI TR 103 087 (V1.1.1) i.30 to cover the following: Remote attestation of the Reconfigurable Equipment status (installed RA and DoC). Configuration enforcement of reconfigurable equipment. Distribution and enforce

47、ment of mobility policies. Long-term management of devices (in particular orphaned devices). Secure device root of trust. 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Informative references References are either specific (identified by da
