A student researching cryptography has taken notes:
• Cryptography protects information through mathematical encoding • Ancient civilizations used simple substitution ciphers • Modern encryption relies on computationally difficult problems • Public key encryption enables secure online transactions • Quantum computers may eventually break current encryption
The student wants to explain how encryption has evolved.
Quantum computers may eventually be able to break current encryption methods.
Encryption evolved from ancient substitution ciphers to modern systems using computationally difficult problems and public key methods for secure transactions.
Ancient civilizations used simple substitution ciphers to encode messages.
Public key encryption enables secure online transactions today.
Correct Answer: B
Choice B. Ancient ciphers to modern computational methods shows evolution.
