Physical Security Assessment of Advanced Packaging Structures

The demand for System-in-Package (SiP) devices become more prevalent in various critical and industrial applications. As a result of this growing popularity, SiP devices are becoming more attractive to attackers who are seeking to exploit vulnerabilities. Chip security is one of the cornerstones of hardware security and has received considerable attention over the past two decades. With advances in SiP-enabled advanced packaging technology, a new concept called “security packaging of integrated circuits” has been developed to protect chips. This paper provides an in-depth analysis of SiP chip security packaging. In order to accomplish this, we explore MIP sample preparation technique in an effort to ensure that vulnerable locations can be accessed. Finally, by identifying potential vulnerable interfaces, we evaluate the effectiveness of existing security measures, ensuring protection and integrity of the SiP devices.
