Which of the following statements regarding symmetric and asymmetric cryptography la NOT correct?
A.
Symmetric cryptography uses one key. whereas asymmetric cryptography uses two keys (a public and a private key)
B.
Symmetric cryptography is op to 10.000 Times slower than asymmetric cryptography
C.
Symmetric cryptography provides data confidentiality and integrity, whereas asymmetric cryptography provides data confidentiality, authenticity and irrevocability
Definition: Uses a single key for both encryption and decryption.
Speed: Typically faster than asymmetric cryptography due to simpler mathematical operations.
Use Cases: Suitable for encrypting large amounts of data, such as in file encryption.
Asymmetric Cryptography:
Definition: Uses a pair of keys – a public key for encryption and a private key for decryption.
Speed: Generally slower than symmetric cryptography due to more complex mathematical operations.
Use Cases: Ideal for secure key exchange, digital signatures, and encrypting small amounts of data.
NIST SP 800-57: Provides guidelines on key management, highlighting the differences in speed and use cases between symmetric and asymmetric cryptography.
ISO/IEC 18033-1: Specifies cryptographic algorithms and outlines the performance characteristics of symmetric and asymmetric cryptography.
Cybersecurity References:Symmetric cryptography is faster than asymmetric cryptography, making the statement about symmetric cryptography being up to 10,000 times slower incorrect.
