A Security Officer on a military base needs to encrypt several smart phones that will be going into the field.
Which of the following encryption solutions should be deployed in this situation?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
The best encryption solution to deploy in this situation is D. AES-256.
AES-256 (Advanced Encryption Standard-256) is a symmetric encryption algorithm that uses a 256-bit key. It is widely used for encryption and decryption of sensitive data because of its high security and efficiency. AES-256 is considered one of the most secure encryption algorithms, as it would take an impractical amount of time to brute-force attack the encryption.
Elliptic curve encryption is a type of public-key encryption that uses the mathematics of elliptic curves to generate keys. It is useful for encrypting data in situations where a secure channel for key exchange is not available. However, it is not as widely used as symmetric encryption algorithms like AES-256 for encrypting large amounts of data.
One-time pad encryption is a type of symmetric encryption that uses a randomly generated key that is only used once. While it is theoretically unbreakable, it is not practical for encrypting large amounts of data due to the need for a pre-shared secret key that is as long as the data being encrypted.
3DES (Triple Data Encryption Standard) is a symmetric encryption algorithm that uses three separate 56-bit keys to provide a total key length of 168 bits. While it was widely used in the past, it has been largely replaced by AES-256 due to its slower processing speed and lower security.
In summary, AES-256 is the best encryption solution to deploy in this situation due to its high security and efficiency.
