What is the role of hardware security modules in mobile devices?

Hardware security modules (HSMs) are secure physical devices that help safeguard sensitive keys and perform cryptographic operations to enhance the overall security of various systems and devices. HSMs are designed to securely store, protect, and manage keys used for cryptographic algorithms, digital signatures, secure communications, and more. By offloading key management and cryptographic operations to dedicated hardware, HSMs provide a higher level of security compared to software-based solutions. Overall, HSMs play a crucial role in securing sensitive data and ensuring the integrity and confidentiality of cryptographic operations.
