Design Of Bluetooth Security Platform And Research Of Security Transmission

With the widely application of Bluetooth technology, the security of bluetooth technology becomes the hotspot of the industry, especially the problem of security data transmission by bluetooth arouses users' great attention. But lack of the suitable bluetooth platform restricts thorough research of the problem.A platform which can provide the application and research of bluetooth security is designed in this paper. It provides the hardware and firmware for the research of Bluetooth security. It has processor control module,FPGA algorithm module Bluetooth module and basic bluetooth security test firmware. It also supports embedded operating system.On the basis of the security platform, the simple paring protocol which has security leaks has been studied. An improved simple pairing protocol is proposed in this paper. Then the security of the improved simple pairing protocol is proved by Spi calculus. It solves the MITM attack and interference attack of simple pairing protocol.According to the improved simple pairing protocol and the process of Bluetooth transmission which has hidden trouble, the Bluetooth security transmission model is proposed. The EHCI encryption scheme's location is designed according to the Bluetooth security mechanism, the encryption algorithm in the model is optimized. Then the security of the model is analyzed by the MOAT method.Finally, the security platform of Bluetooth is implemented. Then the improved simple pairing protocol and security transmission model is verified. Experiments demonstrate that the security platform can provide reliable and general support for the research of Bluetooth security and application problems, the protocol can protect the security of Bluetooth devices pairing and the model can assure the confidentiality and integrity of the data.
