In an insecure quantum chan-nel that Bob communicates with Alice, we provide a cryptosystem allowing Alice to encrypt and authenticate an n-qubit message by 2n qubits with probability at least 1 − 1 2 O(n) that Alice and Bob can de-tect eavesdropper(Eve), and we prove our quantum cryptosystem has perfect secrecy, that is, we can guarantee that nobody can steal any useful information from encrypted message. |
