A shared language for all processors

As greater frequently than not, the software jogging on a tool remains the producer's corporate mystery, researchers on the Chair for gadget security at Ruhr-Universität Bochum do now not analyse the authentic supply code, but the binary code of zeros and ones that they could study without delay from a tool.

But, unique gadgets are equipped with processors with exclusive complexities: whilst an Intel processor in a laptop is familiar with greater than 500 instructions, a microcontroller in an digital key's able to technique merely 20 commands. an additional hassle is that one and the same preparation, as an example "add two numbers," is represented as one of a kind sequences of zeros and ones in the binary language of  processor types. This renders an automatic evaluation of many specific gadgets hard.

As a way to carry out processor-independent safety analyses, Thorsten Holz' crew interprets the extraordinary binary languages right into a so known as intermediate language. The researchers have already efficaciously applied this method for 3 processor types named Intel, ARM and MIPS.
