Abstract
An anti-tamper module is provided for protecting the contents and functionality of an integrated circuit incorporated in the module. The anti-tamper module is arranged in a stacked configuration having multiple layers. A connection layer is provided for connecting the module to an external system. A configurable logic device is provided for routing connections between the integrated circuit and the connection layer. Specifically, the configurable logic device is programmable to create logical circuits connecting at least one of the input/output connectors of the integrated circuit to at least one of the input/output connectors of the connection layer. Configuration information for programming the reconfigurable logic device is stored in a memory within the module.
