摘　　要：ADS-B产生的假目标会严重影响飞行安全,文章针对此情况,提出了一种ADS-B飞机身份认证和数据加密方案,确保飞行目标身份的真实性和通信数据的机密性。该方案考虑到了机载设备的特殊性,提出了一种负载转移的改进RSA签名方案,将机载设备的大部分签名运算转移到了地面设备来完成。同时该方案对地空数据链进行了加密处理,保证了地空通信数据的机密性、完整性和防否认性,可有效抵抗各种假目标和非法数据攻击。Aiming at the situation that the false targets produced by the ADS-B can seriously affect flight safety,this paper proposes an ADS-B aircraft identity authentication and data encryption scheme to ensure the authenticity of the flight target identity and the confidentiality of the communication data.Considering the particularity of airborne equipment,the scheme proposes an improved RSA signature scheme of load transfer,in which most of the signature operation of airborne equipment is transferred to ground equipment to complete.At the same time,the scheme encrypts the ground-air data link to ensure the confidentiality,integrity and anti-denial of the ground-air communication data,and can effectively resist all kinds of false targets and illegal data attacks.
