With a total of 5 patents to his name, Grell's work focuses on enhancing the security and integrity of computer systems.

Latest Patents

One of Grell's latest patents is a computer system comprising a secure boot mechanism. This innovation allows for secure boot processing based on a non-volatile memory that is an integral part of the CPU. This memory cannot be modified once pre-boot information is programmed into it. During a reset or power-on event, execution starts from this internal non-volatile memory, which includes public decryption keys for verifying the signature of a portion of the boot routine. This method ensures a high degree of tamper resistance, particularly against BIOS modifications. Another significant patent involves a secure boot mechanism based on symmetric key encryption. In this system, a symmetric encryption key is incorporated into a non-volatile memory area of the CPU core, which helps prevent tampering by external sources. The pre-boot information is stored internally in the CPU and is retrieved during a reset or power-on event to verify signed boot information using the internal symmetric encryption key.
