摘　　要：为了解决车辆分享钥匙明文发送方式导致的安全隐患问题,该文设计了一种基于加密通讯暗文发送的车辆授权机制,该机制包括软硬件两部分,通过在软件层将授权信息加密,发送时将传送码通过手机终端APP中按钮封装的服务器传输方式进行暗文发送,成功地避免了秘钥信息的明码裸露,有效地增强信息传输的安全性,极大地增加了非法人员破译的难度,通过层层加密,为安全保驾护航,保护车主和被分享者的财产及人身安全。In order to solve the safe problem that vehicle sharing key clear text sending leads to, this paper introduces the vehicle authorized mechanism based on encryption communicated dark texts sending, this mechanism includes both hardware and software, the authorized information is cryptographed through software layer, the transfer code is sending in the form of the dark text sending through the terminal of phone APP, successfully avoiding the plain code bare for the secret key information, effectively enhancing the security of information transmission, greatly increasing the difficulty of the illegal personnel decipherment, the layers of encryption can guarantee security, ensure the vehicle owner＇s property and personal safety.
