Because Bluetooth uses radio waves to transfer information, it is very susceptible to attacks and due to the lack of security in today’s applications. So providing secure services in those applications is an important issue.
因为蓝牙使用无线电波传输信息,对各种攻击就更加敏感,而当今的很多应用都对安全性有很高的要求,所以如何在这些应用中提过安全服务就是一个非常重要的课题。
