![]() ![]() Generation of the key must be done via true randomness.If the keybits are leaked at any point in the future, the attacker can decrypt all historical messages. Since the key must be stored at both the sending and receiving end, it must be securely destroyed at both ends after use.Once bit \(n\) has been read from the CD, it should never be used to encrypt any other data. The key must be kept secure (both before, during, and long after encryption).One can never be sure whether the person/organisation at the other end of the channel followed procedures correctly to secure the keybits. So all of these issues must be dealt with at each end. The key must be stored at both the sender and receiver’s end.If you spot any mistakes, please leave a comment in the Disqus box at the bottom of the page. I haven’t yet verified this solution independently. Address issues such as life cycle of the key, storage of the key during the life cycle/after the life cycle, key distribution, generation of the key, etc. Discuss the real-life implications of a One-Time-Pad (OTP) system.
