Forensics Module and Embedded System

Abstract

According to various embodiments, a forensics module (250) for an embedded system may comprise: a secured memory area (202s) comprising first data implementing a key (305s); an interface (208) for reading (301) second data (302) representing a system state of the embedded system (150); and one or more than one processor (204) configured to: read (301) the second data (302) by means of the interface (208), wherein the second data (302) comprises a plurality of data sets; determine (303) a commitment (310) to a plurality of aperture values, each aperture value being associated with exactly one of the plurality of data sets, based on the second data (302) and using a cryptographic commitment process configured such that each data set may be individually verified using the commitment (310) and the respective associated aperture value; encrypt (305) the second data (302) and the plurality of aperture values using the key (305s).
