Hardware Security Module Cryptosystem Using Petri Net

An embedded system is a combination of hardware and software designed to perform specific functions. It consists SoCs (system on chip) that it relies do its computing work. A key feature an consumes less power components occupy space the IC (integrated circuit) thus, use SoCs. Embedded manufacturers get these from third-party companies reduce their time market. That would increase possibility systems be compromised. In this paper, we present novel approach securing such critical systems. For that, made Hardware Security Module (HSM), which secure SoC with encrypt/decrypt engine Petri net for algorithm modulation data flow. We ensure uses genuine firmware secured since algorithms only known manufacturers.
