Abstract: Aiming at the problem that Bluetooth Low Energy is vulnerable to DoS Attack, an alive degree model combining entropy theory was established. Bluetooth Low Energy DoS Attack detecting scheme based on this model was designed. The scheme chose some elements to construct alive volume, which showed the stable distribution in normal communications, and the distribution was destroyed when subjected to DoS attacks. Using alive degree to reflect the distribution of alive volume, the DoS Attack was detected via the variation of alive degree. The theory analysis and experiment results show that, the scheme can effectively detect the DoS Attack in the communication with low storage and calculation overhead, which is suited for Bluetooth Low Energy.

Key words: Bluetooth Low Energy, DoS Attack detecting, alive volume, alive degree
