Sample Cryptography Assessments question Test your knowledge!

Which of the following cryptographic algorithms is considered to be quantum-resistant?

  • RSA-2048
  • ECC 256-bit
  • AES-256
  • Lattice-based cryptography

Which technique can be applied to ensure non-repudiation in a public-key infrastructure?

  • Symmetric key encryption
  • Public key encryption only
  • Digital signatures
  • Hash functions without keys
  • Two-factor authentication

Elliptic Curve Cryptography (ECC) is used in modern cryptography as an alternative to traditional RSA for public-key encryption. What is the main advantage of using ECC over RSA?

  • ECC offers faster encryption speeds.
  • ECC requires less computational power.
  • ECC can deliver the same security with smaller key sizes.
  • ECC has a simpler algorithm, making it easier to implement.
  • ECC uses integer factorization, which is proven to be secure.

In cryptography, what is the primary function of a 'nonce'?

  • To provide a public key for asymmetric encryption
  • To verify the authenticity of a digital signature
  • To enhance security in a block cipher by introducing randomness
  • To decrypt a message by providing the corresponding private key
  • To increase hashing speed when generating message digests

What cryptographic principle does the 'Avalanche Effect' relate to?

  • The property of a good hash function where a small change in input results in a significant change in output
  • The expansion of plaintext into longer ciphertext for transport security
  • The rapid generation of cryptographic keys using a seed
  • The aspect of a public key infrastructure (PKI) regarding certificate revocation
  • The separation of duties in a multi-user encryption system

Homomorphic encryption is an encryption scheme which allows computation on ciphertexts to generate encrypted result that, when decrypted, matches the result of operations performed on the plaintexts. Which use case is a practical application of homomorphic encryption?

  • Secure multi-party computation without revealing any party's inputs
  • Broadcasting messages that only certain people can decrypt
  • Generating random numbers for cryptographic applications
  • Verifying the integrity of a message without knowing its contents
  • Improving the efficiency of symmetric key algorithms
