Strengthening SoC Protection with Hardware-Based Secure Storage and OTP Technology

As connected devices in AI, IoT, automotive, aerospace, and high-performance computing become more advanced, security threats are increasing rapidly. Software-only security solutions are no longer enough because many attacks target vulnerabilities below the software layer. Hardware-based security provides a stronger defense by creating a root of trust directly in the silicon, often using technologies like Physical Unclonable Functions (PUFs) to generate unique device keys and protect sensitive data.

Embedded One-Time Programmable (OTP) non-volatile memory is widely used to securely store encryption keys and critical boot code in modern chips. Antifuse-based OTP technology offers stronger resistance to traditional hacking methods compared to older fuse-based approaches. However, advanced attacks can still target OTP memory, which is why additional hardware security layers are needed to fully protect sensitive information and maintain system integrity.
