Question

Why is it important to directly access the hardware time-stamp counter using a low-level instruction in the Processor Time-Stamp Verification Thread?

a.

So that the program can be loaded in a disassembler and the code can be easily read.

b.

So that crackers cannot hook or replace the function that obtains the value.

c.

So that live debugging can be performed more easily.

d.

So that the program can be run on different hardware configurations.

Answer: (b).So that crackers cannot hook or replace the function that obtains the value. Explanation:The direct access to the hardware time-stamp counter using a low-level instruction such as RDTSC makes it difficult for crackers to hook or replace the function that obtains the value, which helps to make the process of live debugging on the protected application more difficult.
