A quantum key distribution protocol is secure if it is ''correct'' and ''secret''. Correctness is the statement that Alice and Bob share the same string of bits, namely the secret key, at the end of the protocol. Secrecy is the statement that the eavesdropper is totally ignorant about the final key. | A quantum key distribution protocol is secure if it is ''correct'' and ''secret''.
