汽车中的TPMS发出未经加密的信号,让陌生人不经同意跟踪车辆,引起对隐私的重大关切。 TPMS in cars emits unencrypted signals, letting strangers track vehicles without consent, raising major privacy concerns.

研究人员发现,现代车辆的轮胎压力监测系统(TPMS)发出无加密无线电信号,带有独特的身份证,使拥有100美元接收器的任何人可以不经同意跟踪汽车。 Researchers have found that tire pressure monitoring systems (TPMS) in modern vehicles emit unencrypted radio signals with unique IDs, allowing anyone with a $100 receiver to track cars without consent. 十周多来,他们从20 000部车辆中收集了600多万个信号,准确监测了距离50多米的移动和日常活动,甚至通过墙壁。 Over ten weeks, they collected over 6 million signals from 20,000 vehicles, accurately monitoring movements and routines from over 50 meters away, even through walls. 由于TPMS是为安全(而不是安全)设计的,现行条例没有解决这些隐私风险,使司机容易被黑客、罪犯或制造商追踪。 Since TPMS was designed for safety—not security—current regulations don’t address these privacy risks, leaving drivers vulnerable to tracking by hackers, criminals, or manufacturers. 专家们敦促汽车制造商和政策制定者加强车辆传感器系统的安全标准。 Experts urge automakers and policymakers to strengthen security standards for vehicle sensor systems.
