According to literature, version 2.0 optionally allows for package signing which mitigates this flaw. Another source mentions that MAVLink 2.0 only provides a simple authentication system based on HMAC. This implies that the flying system overall should add the same symmetric key into all devices of network. If not the case, this may cause a security issue, that if one of the devices and its symmetric key are compromised, the whole authentication system is not reliable."}, {"lang": "es", "value": "El protocolo Micro Air Vehicle Link (MAVLink) no presenta ning\u00fan mecanismo de autenticaci\u00f3n en su versi\u00f3n 1.0 (ni autorizaci\u00f3n), lo que conlleva a una variedad de ataques que incluyen suplantaci\u00f3n de identidad, acceso no autorizado, ataques PITM y m\u00e1s.
