摘要： An anti-tamper device (10) for one or more integrated circuits (12) includes a firing assembly (14) and a breach assembly (16). The firing assembly (14) includes a contained energy source (24), an impact element (26) and a breach assembly (16). The breach assembly (16) is configured to house one or more integrated circuits (12) and a propellant charge (30). Upon an attempt to improperly remove or dislodge an integrated circuit (12) from the anti-tamper device (10), the contained energy source (24) is actuated. The energy source (24) propels the impact element (26) against the propellant charge (30), causing the charge to ignite. The resultant forces from the impact element (26) and ignition of the charge imparts a shock wave through the anti-tamper device (10). This shock wave induces spalling of the integrated circuit (12) such that the circuit is physically altered and rendered unreadable.

摘要翻译： 用于一个或多个集成电路（12）的防篡改装置（10）包括发射组件（14）和缺口组件（16）。 发射组件（14）包括容纳的能量源（24），冲击元件（26）和缺口组件（16）。 该突破组件（16）被配置为容纳一个或多个集成电路（12）和推进剂装药（30）。 在试图从防篡改设备（10）不正确地移除或移除集成电路（12）时，所包含的能源（24）被致动。 能量源（24）推动冲击元件（26）抵抗推进剂装药（30），引起装药点燃。 来自冲击元件（26）的合力和电荷的点燃通过防篡改装置（10）产生冲击波。 该冲击波引起集成电路（12）的剥落，使得电路物理改变并且变得不可读。
