Two avowable quantum communication schemes are proposed.One is an avowable teleportation protocolbased on the quantum cryptography.In this protocol one teleports a set of one-particle states based on the availabilityof an honest arbitrator,the keys and the Einstein-Podolsky-Rosen pairs shared by the communication parties and thearbitrator.The key point is that the fact of the teleportation can neither be disavowed by the sender nor be denied bythe receiver.Another is an avowable quantum secure direct communication scheme.A one-way Hash function chosenby the communication parties helps the receiver to validate the truth of the information and to avoid disavowing for thesender.
