Ringkasan	The Diffie-Hellman key exchange, invented by Whitfield Diffie and Martin Hellman in 1976, is a foundational protocol for establishing a shared secret over an insecure communication channel. Two parties who have never previously communicated can use Diffie-Hellman to agree on a symmetric encryption key that an eavesdropper cannot easily derive, even after observing all public exchanges.	Symmetric key cryptanalysis is the study of attacks against symmetric encryption algorithms (such as DES, AES, and stream ciphers) to evaluate their security and identify weaknesses. Classical techniques include differential cryptanalysis and linear cryptanalysis, which have shaped the design of modern ciphers and remain essential tools for cryptographers assessing algorithm robustness.
