Arbitrated Secure Authentication realized by using quantum principles

Unconditionally secure authentication schemes with an arbiter have been proposed in the literature. We extend this idea in the context of quantum authentication. In this paper, we present an unconditionally secure authentication scheme with an arbiter by using quantum principles. Compared to other arbitrated quantum schemes, our scheme is secure against denial by the sender of having sent a message (non-repudiation property) and also secure against a malicious receiver. We consider the problem of authenticating a classical message in the presence of a semi-honest arbiter. The shared secret keys can be reused, in contrast to several other proposed arbitrated quantum schemes.
