Original Abstract Submitted
A system on a chip (SOC) includes a user space having one or more cores, and a hardware security engine (HSE). The HSE includes storage circuitry configured to store an SOC configuration table. The SOC configuration table is configured to store, in a first entry, a current and valid configuration record corresponding to a current configuration of the SOC. The HSE is configured to, in response to an update service request from a core of the user space, decrypt an encrypted file to obtain new configuration data, update a blank record in a second entry of the SOC configuration table to be the current and valid configuration record storing the new configuration data, and update the current and valid configuration record in the first entry to be a previous and valid configuration record.
