摘要/Abstract

摘要：

移动边缘计算可支撑多类高可靠、低时延的海事应用，然而计算任务的卸载存在诸多安全隐患。为此，分析并量化了海洋移动终端由任务卸载导致的位置隐私泄露风险。建立有关位置隐私保护模型并提出一种基于动态缓存与空间匿名的位置隐私保护（DS-LPP, dynamic cache and spatial cloaking-based location privacy protection）算法。仿真结果表明，DS-LPP 算法在保护海洋移动终端位置隐私时，相比传统算法优构建匿名空间与中继节点选取性能更优，因而可有效应用于通信、计算资源相对匮乏的海洋观监测传感网，保障终端位置隐私保护连续性。

Abstract:

Mobile edge computing can support various maritime applications with high reliability and low delay.However, many security problems in computing task offloading exist.The risk of location privacy leakage of maritime mobile terminals during task offloading was analyzed and quantified.The related location privacy protection model was established and a dynamic cache and spatial cloaking-based location privacy protection (DS-LPP) algorithm was proposed.Simulation results show that DS-LPP algorithm has better performance of constructing anonymous space and selecting relay node than traditional algorithms while protecting the location privacy of maritime mobile terminals.Therefore, the DS-LPP algorithm can be effectively applied to maritime monitoring sensor network with relatively scanty communication and computing resources, and ensure the continuity of location privacy protection.

Key words: maritime monitoring sensor network, mobile edge computing, location privacy protection, task offloading
