The answer is A- Mobile Wallet
It can be used to pay for your purchases instead of using your actual card. It may be an app or it may be already built into the device. It is actually more convenient to others because you can just hold your device at the terminal when you will pay. Mobile Wallets may be smartphones or tablets.
Are you going into space... if so well... space, that is the big issue
DES is a commonly used symmetric encryption
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.
