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.
The sum would be 31/7, or 4.428571428571429 in decimal form.
Data mining is an information analysis tool that involves the automated discovery of patterns and relationship in the data warehouse.
