USB network card data encryption and decryption method based on RNDIS

The invention provides a USB network card data encryption and decryption method based on RNDIS. According to the method, the to-be-transmitted data is encrypted, and the network transmission is carried out in a ciphertext transmission mode, so that the security and integrity of the data can be effectively ensured, the user signature is added in the data message, the user identity information is clear, and false data is prevented from being received. 本公开提出基于RNDIS的USB网卡数据加解密方法，所述方法通过对待传输数据进行加密处理，以密文传送的方式进行网络传输，能够有效保证数据的安全以及完整性，同时在数据报文中增加用户签名，明确用户身份信息，避免接收虚假数据。
