Assymmetric Encryption: Why can a message encrypted with the Public Key only be decrypted with the receiver’s appropriate Private Key?
✓
Correct Answer
B. A so called “one way function with back door” is applied for the encryption
💡
Explanation
An one-way function is a function which a computer can calculate quickly, but whose reversal would last months or years. An one-way function with back door can be reversed with the help of a couple of additional information (the back door), but scarcely without this information. The information for the back door is contained in the private Key.
