HSM4 is a hardware security module designed to protect embedded single board computers used in custom OEM applications. HSM4 provides all the great security features of our popular ZYMKEY4 product, encapsulated in a secure module with hidden 30 pin connector. This innovative packaging reduces the attack surface and simplifies integration into custom OEM boards and manufacturing workflows. For prototyping and evaluation, developer hats are available for Raspberry Pi and Nvidia Jetson. Example code and online documentation provide a simple low-risk way to integrate multiple layers of security into your application. Software APIs are available in Python, C and C++, with support for Ubuntu and Raspberry Pi OS.

HSM4 is a hardware security module designed to be embedded into custom OEM applications. It provides multiple layers of security that protect against cyber and physical exploits. Sensitive key material is generated and stored in a secure element with micro-grid protected silicon. A separate security supervisor isolates the secure element from the host computer and provides additional layers such as multi-factor measured identity and authentication of host system, multi-sensor physical security and real time clock.
