    "abstract": "The problem of security of quantum key protocols is examined. In addition to\nthe distribution of classical keys, the problem of encrypting quantum data and\nthe structure of the operators which perform quantum encryption is studied. It\nis found that unitary bases are central to both encryption of quantum\ninformation, as well as the generation of states used in generalized quantum\nkey distribution (which are called mutually unbiased bases). A one-to-one\ncorrespondence between certain unitary bases and mutually unbiased bases is\nfound. Finally, a new protocol for making anonymous classical broadcasts is\ngiven along with a security proof. An experimental procedure to implement this\nprotocol is also given. In order to prove these new results, some new bounds\nfor accessible information of quantum sources are obtained.",
