The complexity of today’s multiprocessor System-on-Chip (MPSoC) can lead to major security risks in embedded designs, as the available security functions are often not or insufficiently utilized.

InES (Institute of Embedded Systems at ZHAW) developed a reference design which demonstrates a concept of a secure boot implementation and runtime system on a Xilinx Zynq Ultrascale+.

The security concept includes dedicated on-chip security features like AES, RSA and hashing core. The reference design also describes how to implement a voltage and temperature tamper detection. In addition, secure key storage and various methods to minimize key usage are provided. The demonstrator implements the ARM Trust Zone technology with OP-TEE as a secure operating system.

Implementation examples and usage description of the Linux Crypto-API, using the dedicated cryptographic cores, are also included in the documentation.

The modular open-source reference design is provided on GitHub, which contains implementation examples for all the above features.
