基于北斗卫星导航系统的安全芯片设计

Security IC design based on the Beidou satellite navigation system

在万物互联时代,针对联网设备的位置和时间攻击越来越普遍,为了增强联网设备的抗攻击能力,在北斗卫星接收技术的基础上,设计出位置和时间自检单元、实时监控单元、安全报警单元等,使位置传感器和时间传感器具备了不可篡改性、不可旁路性等安全传感器的特性,并与传统的安全技术相结合,设计出具有位置传感器和时间传感器的安全芯片,满足了设备对位置和时间防护的需求,并且填补了国内外在安全芯片设计领域的技术空白。

In the era of Internet of Everything,information security is becoming more and more important. It is getting common to see the attacks to position and time domains of those devices which are connected to the Internet. To strengthen the devices＇ immunity against the attack,a novel solution,on the basis of the Beidou satellite reception technology,is proposed. This solution includes the position and time self-check unit,real-time monitoring unit and security alarm unit. Those units act as the position sensor and time sensor having irreversible and non-bypass characters and having those characters inside traditional security chip. The proposed security IC meets the needs of protection to the position and time attacks,which are seldom considered in the past at home and abroad.
