Secure Communications

The video tutorial explains the one-time pad encryption method, which ensures secure communication by using a random cryptographic key. The key must be as long as the message, shared secretly between parties, and used only once to prevent statistical patterns. The tutorial highlights the importance of key sharing and the risks of eavesdropping if the key is compromised.

Explain how a meaningful binary string is used in the one-time pad method.

What is the significance of the key in a one-time pad encryption?

How does an eavesdropper's inability to decipher the message relate to the randomness of the key?

Describe the conditions that must be met for the one-time pad to be secure.

What happens if the key is reused in one-time pad encryption?
