A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.
Answer:
Option (a), (d) and (e) is the correct option to the following question.
Explanation:
Because most of the application is that type which consuming a lot of power because of their features and the functionality and also these applications have large in size. The mobile phones also consume power when the brightness of the mobile is set at a high level and also when its VPN is connected or connected through the WIFI.
