A small business needs to encrypt files on a shared network drive. They want a solution that is fast and does not require a complex key management infrastructure. Which cryptographic approach is most suitable?

Use a hybrid approach with a different key for each file.

Use asymmetric encryption with a public/private key pair for each file.

Use a hash function to encrypt the files.

Use symmetric encryption with a single shared key.

What is the primary threat that quantum computing poses to current cryptographic methods?

It can efficiently solve the mathematical problems underlying asymmetric algorithms like RSA and ECC

It can break symmetric encryption like AES by brute force faster than classical computers

It can alter encrypted data without detection

It can intercept and read encrypted data without the key

A security architect is evaluating cryptographic solutions for a system that must protect data for the next 20 years. The architect is concerned about the potential for quantum computers to break current algorithms. Which strategy is most appropriate?

Use RSA-4096 for key exchange and digital signatures.

Implement a hybrid approach using ECC and a post-quantum algorithm.

Use only Quantum Key Distribution for all data encryption.

Use AES-256 with a 256-bit key and rely on its security.
