Abstract: Abstract Location privacy protection algorithm based on Euclidean space cannot be applied to road network environment. In addition, replay attack under road network environment is also an important problem of restricting its application. On the premise of satisfying k anonymity and L road segment diversity, this paper proposes conditions of preventing replay attack under road network environment and testifies the correctness. Besides, a road segment hiding algorithm based on binary tree is designed. The experimental results prove the effectiveness of this algorithm and the algorithm can reduce the hiding time. However, in order to prevent replay attack, query time of the algorithm increases. Generally speaking, an effective and correct method is provided for protecting the user’s location privacy under road network environment and effectively preventing replay attack.
