Abstract


Bluetooth technology as a unified global standard for wireless communications , is to establish a common low-power , low-cost radio air interface and control software open standards , different manufacturers of portable devices in the case of no cable connected to each other in the past distance range interoperability , interoperable performance . Therefore, the research the Bluetooth security authorization and access control technology to improve the safety performance in the Bluetooth application has important significance. Bluetooth technology to ensure safe performance in the link layer and application layer security mechanisms, defines four kinds of safe mode and two types of security levels for data transmission . Bluetooth Security White Paper gives a viable security system , which provides a very flexible security framework is built on top of the Bluetooth direct link -level security . Bluetooth security architecture have some flexibility , Bluetooth devices registered , request authentication ( authentication ) , authorization , encryption , secure data transmission . A high level of security applications in some occasions , such as the use of Bluetooth technology for military communications, e-commerce and government communication , the user identity authentication and data transmission security need to be further strengthened . Bluetooth is committed to global operability and inexpensive , compact structure and other factors to consider , so it does not emphasize advanced technology . Bluetooth protocol , there are some security flaws Bluetooth authentication mechanism is used to identify the device and not used to identify users . Cross-license allows access control , and only when the plan to connect the Bluetooth protocol support the connected device rather than a specific user . The solution to this problem is to introduce a technique called \the user is not authorized to enter the network , and thus can provide different access rights for different users .
