Cryptography metasurface for one-time-pad
WebJul 12, 2024 · In cryptography, the One Time Pad is an encryption technique in which a secret key of length more than or equal to that of the plaintext message is used to encrypt the message. The secret key is randomly generated and it is pre-shared with the communicating parties. WebApr 15, 2024 · Lecture 71: Purifying protocols using entanglement - Quantum Cryptography量子密码学
