Symmetric cryptography (e.g., AES) uses a single key for encryption and decryption, offering speed for large data but risking security during key sharing. Asymmetric cryptography (e.g., RSA) uses public-private key pairs for secure key exchange without prior sharing, though it's slower for bulk encryption.
| Symmetric Cryptography | Asymmetric Cryptography |
|---|---|
| Uses the same key for both encryption and decryption (e.g., AES). Fast and efficient for large data volumes, but key sharing poses security risks. | Employs public/private key pairs (e.g., RSA). Enables secure key sharing without prior exchange, but computationally slower for bulk encryption. |
Quantum computing uses qubits that exploit superposition for multiple simultaneous states and entanglement for instantaneous qubit correlations. Unlike classical bits, it enables parallel computations with exponential speedup for specific problems.
This section header slide, titled "Quantum Computing and Cryptography," introduces "Quantum Threats to Encryption." Its subtitle explains how quantum power breaks current crypto standards.
How quantum power breaks current crypto standards
Shor's Algorithm factors large numbers exponentially faster than classical methods, cracking RSA public-key systems in polynomial time. It also breaks ECC cryptosystems via efficient discrete logarithms, threatening asymmetric encryption on quantum hardware.
This slide visualizes Grover's algorithm's quadratic speedup for quantum brute-force attacks on symmetric keys. It highlights AES-256's security halving to 128-bit equivalent, urging migration to quantum-resistant key lengths.
