WebApr 14, 2014 · 10. A one time pad offers information theoretic security. This essentially means that the one time pad cannot be broken even if the adversary has unlimited computing power. This is because XOR-ing any data against a truly random key will guarantee that the output be random as well because you are simply flipping bits.

Designed in... Creative Escape Rooms LLC 2kfollowers More information In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a plaintext is paired with a random secret key (also referred to as a one-time pad).
