Security enhancement scheme for mobile device using H/W cryptographic module

This paper is about a mobile device security enhancement technology using a hardware cryptographic module. More specifically, it is a technology that provides an encryption function to access networks such as private networks and national defense networks that require a higher level of security. The hardware cryptographic module is a separate hardware device physically independent of the mobile device. It provides not only basic encryption functions such as data encryption, message authentication, and digital signature, but also security functions such as identification and key management, authentication, and secure storage in conjunction with the built-in Physical Unclonable Function (PUF).
