Researchers at the University of Florida and University of Central Florida have published a technical paper titled "GATE-SiP: Enabling Authenticated Encryption Testing in Systems-in-Package".
The paper proposes GATE-SiP, an authenticated partial encryption protocol for secure testing in heterogeneous integrated Systems-in-Package (SIP) systems.
GATE-SiP ensures that sensitive testing data designated for a specific chiplet is only sent to the authenticated chiplet, preventing blocking, tampering, or sniffing by malicious chiplets.
Simulation results demonstrate that GATE-SiP protocol incurs minimal penalties on area and timing overhead, with only 6.74% and 14.31% increase, respectively.
