Shared Key Based Dynamic Encryption Scheme for Secure Bluetooth Technology

Abstract Bluetooth (BT) is a wireless technology which is used for reduces cable in network. BT is developed for the legal term of companies for an open specification for connection of wireless in short range. BT technology requires low power; low costs and easily interfaces with exiting device. That is the reason BT can easily be hack or crack. Therefore, security is the measure problem with this technology. In this article we have suggested a novel security algorithm for establishing shared link key between pico-nets, and scatter net communication. It is capable of authenticating scatter nets peers that are not directly connected with node. For secure transmission of packets among pico-nets and scatter nets will be devised. In addition, obfuscation technique affects the performance of the code as it may change the whole layout of the program structure. In this paper we have shared a key in each data packet transmission of dynamic encryption for Bluetooth technology.
