What should be a good measure to build additional security on top of underlying 615A protocol?ĭigitally signing the data with a digital certificate could be a option that we are considering? but will that be a good option as this is not a internet connected set up to validate the certificate etc. however threat we want to address is if a malicious data loader machine is connected which loads the malicious data to aircraft. This is a point to point Ethernet connection and not connected to internet or any other network. offers secure ARINC 615 Portable Data Loader (PDL) solutions for management of avionic software parts using the ARINC 615 and 615A data. Our primary intent is to address Authenticity and Integrity! We however would be using underlying standard protocol of 615A & 665 and intend to build additional security on top of it.Ĭonfidentiality is not a concern here so we don't need to encrypt the data which is being transmitted. Since ARINC 615A doesn't seem to provide a full proof secured communication (uses and TFTP protocol over UDP/IP and CRC check), we intend to make this function fully secured. COMMENTARY Equipment manufacturers should note that this document aims to encourage them to optimize the characteristics of the data loader ease of use, cost, maintenance. It describes a data load protocol implemented using Trivial File. ARINC Report 615A is also being used to load avionics over other avionics buses using elements of the Ethernet protocol (e.g., ARINC 615A over AFDX ARINC 615A over CAN Bus). 615A specifies high speed Ethernet based data load operation where POINT-TO-POINT Ethernet connection between Data loader device and target machine in Aircraft. AITs ARINC 615 and ARINC 615A data loader software is compatible with all AIT ARINC 429, ARINC 664, & Ethernet interface modules and can be integrated into. ARINC 615A is an ARINC report called Software Data Loader Using Ethernet Interface. There is Avionics standard termed as ARINC 615A and ARINC 665. We have a requirement for Data loading function to Aircraft.
