A Trusted Boot Scheme for UAS Based on Cross-device Chain of Trust
In order to protect the secrecy and integrity of UAV software,a trusted boot scheme for UAS based on cross-device chain of trust is proposed.According to operation environment of the UAV and the ground station,the root of trust in the UAV is di-vided into two parts,which are confidentiality protection part and integrity protection part,which are stored in the UAV and the ground station separately.During startup,the two devices finished cross-device trusted boot through interactive verification to en-sure system security.By performing multiple signatures on the system software,manufacturers or users are prevented from unilateral-ly tampering with the system.The experiment shows that the scheme can meet the requirements for software secrecy and integrity in the UAS.
