One of the challenges for a successful commercial deployment of Reconfigurable Radio Systems (RRS) technologies is to provide an adequate level of security. While RRS should guarantee the same level of security of conventional wireless communication systems, they may also present new vulnerabilities or security threats. The intent of this Work Item is to complete the previous set of security requirements, complementing the exiting TS by taking into account the following RRS use cases: 1) remote attestation of the Reconfigurable Equipment status (installed Radio Application and DoC) 2) remote control of Reconfigurable Equipment status (use case “configuration enforcement of reconfigurable equipment” covering e.g. radio front-end status, RA configuration, and cognitive radio operational mode) 3) distribution and enforcement of mobility policies 4) management of orphaned devices
