Question

Because of the large key size, brute-force attacks on AES are what?

1) Infeasible
2) Efficient
3) Ineffective
4) Impossible

Answer 1

Due to the extensive key sizes available in AES encryption, including 128, 192, and 256 bits, a brute-force attack becomes infeasible, requiring an impractical amount of computational power with today's technology.

Step-by-step explanation:

Because of the large key size, brute-force attacks on AES are infeasible. The Advanced Encryption Standard (AES) is a symmetric encryption algorithm widely used across the globe to secure data. AES comes in three key sizes: 128, 192, and 256 bits, with AES-256 being the strongest. Given the exponential growth in possible keys with increasing key size, a brute-force attempt to crack AES would require an astronomical amount of computation, rendering such an attack practically impossible with current technology. Therefore, out of the options, 'Infeasible' is the correct term to describe brute-force attacks on AES encryption.
