摘要:

多传感器运行环境复杂化,空间态势信息外界威胁度较高,防篡改机制触发次数较低,敏感性较差且响应时间较长,提出了一种多传感器空间态势信息隐私数据防篡改方法研究。结合隐私数据安全需求,确定密钥分存策略,设置隐私数据加密查询范围。基于多传感器空间态势感知结果和隐私数据查询结果,制定动态防篡改机制,实现多传感器空间态势信息隐私数据的防篡改功能设计。实验结果表明:该方法在不同节点环境下能够快速响应,防第三方篡改机制最小响应时间为1.8秒,单元块触发次数均较低,证实了该方法具备较好的隐私数据防篡改性能。

Abstract:

The operating environment of multiple sensors is complex, and the external threat level of spatial situation information is high. The anti-tamper mechanism has low triggering times, poor sensitivity, and long response time. A research method for privacy data anti-tamper of multi-sensor spatial situation information is proposed. Based on the security requirements of privacy data, determine the key sharing strategy and set the scope of privacy data encryption query. Based on the results of multi-sensor spatial situational awareness and privacy data query, a dynamic anti-tamper mechanism is developed to achieve the anti-tamper function design of multi-sensor spatial situational information privacy data. The experimental results show that this method can respond quickly in different node environments, with a minimum response time of 1.8 seconds for third-party tamper prevention mechanisms, and low triggering times for unit blocks. This confirms that this method has good privacy data tamper prevention performance.
