Tiivistelmä	Return-Oriented Programming (ROP) is an exploit technique that chains together short sequences of instructions (gadgets) from existing executable code to perform arbitrary computation, bypassing security defenses like code injection prevention. Introduced by Hovav Shacham in 2007, ROP exploits code reuse to execute malicious logic even when data execution prevention (DEP) and code signing prevent direct code injection. ROP is considered one of the most powerful exploit techniques against modern defense mechanisms and has been demonstrated to be Turing-complete.	Differential cryptanalysis is a statistical attack technique on symmetric block ciphers that analyzes differences in inputs and outputs to recover secret keys. Introduced by Eli Biham and Adi Shamir in 1990, differential cryptanalysis was the first practical attack on DES that outperformed brute force search. The technique exploits non-random properties of cipher transformations by studying how small changes in plaintext propagate through the cipher rounds. Differential cryptanalysis has shaped cipher design for three decades.
