When accurately executed, the only cryptosystem known to be unbreakable is called: "One-time Pad" (Option D)
<h3>What is a Crypto System?</h3>
The one-time pad is a cryptographic approach that cannot be broken but needs the usage of a single-use pre-shared key that is not less than the message being delivered. A plaintext is coupled with a unique secret key in this manner.
It should be emphasized that in cryptography, a cryptosystem is a collection of cryptographic algorithms that are required to perform a certain security function, such as confidentiality. A cryptosystem is often composed of three algorithms: one just for key generation, one for encrypting, and one for deciphering.
