Patent ID: 11947676
Assignee: SECURE THINGZ LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A processor system being operable by an operating system, the processor system comprising:
a processor;
a first memory area being configured to store a boot program code, wherein the boot program code forms a part of a boot program which is re-usable when the operating system is executed, the boot program code being configured for performing a cryptographic operation when the boot program code is executed by the processor;
a second memory area being configured to store one or more cryptographic keys, wherein the second memory area is only accessible to the boot program code, when the boot program code is executed by the processor;
a third memory area being configured to store the operating system when executed by the processor;
a communication interface being configured to receive data over a communication network;
wherein the processor is configured to retrieve the boot program code from the first memory area, and to execute the boot program code in order to start execution of the operating system, and to terminate the execution of the boot program code while the operating system is being executed by the processor;
wherein the processor is configured to re-execute the boot program code while the operating system is simultaneously being executed in order to cryptographically encrypt the data upon the basis of the cryptographic keys stored in the second memory area; and
wherein the processor is configured to re-execute the boot program code while the operating system is simultaneously exchanging data over the communication interface in order to cryptographically encrypt data for sending or decrypt received data upon the basis of the cryptographic keys stored in the second memory area.
