Abstract

According to one or more embodiments of the present invention, an example computer-implemented method for measuring concurrent updates in a security coprocessor includes using a first set of platform configuration registers of the security coprocessor to store and extend measurement of a code-load used during a boot sequence of a computing device. The method further includes using a second set of platform configuration registers of the security coprocessor to store and extend measurement of configuration parameters of the code-load used during the boot sequence. The method further includes using a third set of platform configuration registers of the security coprocessor to store and extend measurements of a concurrent update that changes the code-load that was used during the boot sequence.
