You are designing an encryption plan for your data while in transit. You want to ensure that your data is protected at every step of the communication path to avoid any malicious party from being able to violate the confidentiality or integrity of your data. You have decided that the protection of your data is far more important than the speed in which it is sent over the network so you are willing to trade communications performance for protection. Which of the following is the best option?

Question $64$ options:

Use an application layer block cipher encryption method to encrypt the data prior to it being sent over any communications path.

Use a stream cipher based link encryption to ensure that your data is encrypted before it leaves your computer.

Use a simple substitution cipher to encode your data then transmit the cipher text over public communications circuits.

None of the above
