Chiplets are gaining significant traction as they deliver numerous benefits beyond what can be accomplished with a monolithic SoC in a time of slowing transistor scaling. However, disaggregating SoCs into multiple chiplets increases the attack surface which adversaries can exploit to penetrate safeguards to data and hardware. With chiplets, the risks of hardware-based trojans and exploits such as man-in-the-middle attacks all rise. To realize the many benefits of chiplets, designers should use a design for security approach, and implement security safeguards anchored in hardware.
Modern vehicles are becoming increasingly complex, driving OEMs to want more modular designs both for integration and for servicing. Being able to rapidly change out components may help with the vehicle servicing, but it also makes it easier for those components to be stolen and resold, creating a safety issue as these parts appear to be genuine but may not function properly.
