Aiming at the main potential safety hazard of data leakage in ACARS data link communication, two ACARS data link information encryption experiment schemes based on an SM4 algorithm and an SM2 algorithm are respectively realized aiming at character-oriented data coding. In addition, according to the invention, an ACARS real message is used for encryption and verification of an algorithm. Experimental test results show that ACARS data encrypted by the domestic password SM4 and SM2 algorithms has certain security. In addition, due to system resource and bandwidth limitation, compared with an SM2 encryption algorithm, the SM4 encryption algorithm is more suitable for the ACARS system to encrypt data link information.
针对ACARS数据链路通信中存在的数据泄露这一主要安全隐患,本发明针对面向字符型的数据编码分别实现了基于SM4算法和基于SM2算法的两种ACARS数据链路信息加密实验方案。此外,本发明还使用ACARS真实报文进行算法的加密和验证。经过实验测试结果表明,经过国产密码SM4和SM2算法加密后的ACARS数据具有一定的安全性。此外,由于系统资源和带宽限制,SM4加密算法相比于SM2加密算法更适合ACARS系统对数据链路信息的加密。
