Question
Which encryption algorithm provides highly secure VPN communications?
Options
- A3DES
- BAES 256
- CAES 128
- DDES
Explanation
AES 256-bit encryption is considered highly secure for VPN communications due to its strong cryptographic key length and resistance to brute-force attacks.
Common mistakes.
- A. 3DES (Triple DES) is an older algorithm that is slower and considered less secure than AES, especially given its smaller effective key size compared to AES-256.
- C. AES 128 is a strong encryption algorithm, but AES 256 offers a higher level of security due to its longer key length, making it the most secure option among the choices.
- D. DES (Data Encryption Standard) is an outdated and insecure encryption algorithm with a 56-bit key, easily breakable with modern computing power, and should not be used for secure communications.
Concept tested. Strong VPN encryption algorithms
