✓
Correct Answer
A. The key indicates which function is used for encryption. Thereby it is more difficult to decrypt an intercepted message as the f
💡
Explanation
The encoding of a message is calculated by an algorithm. If always the same algorithm would be used, it would be easy to crack intercepted messages. However, it isn’t possible to invent a new algorithm whenever the old one was cracked, therefore the possibility to parameterize algorithms is needed and this is the assignment of the key.
