Question

1. One-time Pad. A One-time Pad (OTP) is a secure method of encrypting data, but since each user must have a copy of a file of random key, it is not practical in most situations. The random key for OTP must be truly random, typically generated from a hardware entropy source. What other condition must be met for OTP to be secure? When this condition is not met, what situation arises, and why is it a bad thing?

Answer 1

Other condition that should be met for the one time pad should that the key should be as long as plaintext to avoid the clear difference between the plaintext and the key . The otp should be never reused in the whole part of the process , because it can be clear understandable if some is keeping an eye on all of them . and last consition is the random key should be kept secret in the whole process and should not be disclosed to anyone. If these condition are not met that there might be serious secret issue which can lead to data breach and security breach
