¿µ¹®³»¿ë¿ä¾à The technical specification of VHF data exchange (VDES) has been described in ITU-R M.2092-1. According to this specification, to support high data rate of VDES service, the wireless communication scheme of VDES requires complex communication protocol. Thus rapidly detecting communication errors and urgently managing the effects of invalid VDL transmission are essential to guarantee the reliable VDES VDL service. To improve the reliability of VDES VDL integrity monitoring, this document describes various sources of VDES VDL vulnerability, such as unauthorized signaling, misbehaving devices, incorrect configuration, spoofing attack, protocol attack, and interference signal. Then, to improve the reliability of VDES VDL integrity monitoring, methods to mitigate the effects of invalid transmission have been presented.
