Cryptography one time pad

WebJun 23, 2024 · One time pad (OTP) is a very simple encryption. Its algorithm is like this. Convert the data you want to encrypt into binary (we call this the plaintext). Generate a true random binary array with the same length as your plaintext (we call this the pad). Perform bitwise XOR between the plaintext and the pad, the result is our cipher. WebApr 16, 2024 · Moreover, we can further extend the message space to quantum states by a hybrid encryption with quantum one-time pad as in , i.e., we encrypt a quantum message by a quantum one-time pad, and then encrypt the key of the quantum one-time pad by quantum PKE for classical messages.
