Quantum cryptography including quantum key distribution and quantum secret sharing, a fundamental branch in quantum information processing, is the process whereby two or more parties agree on a key for subsequent cryptographic use. The goal of quantum cryptography is to establish a secure key in an insecure communication environment, leading to the difficulty of the protocols' design and analysis. In this thesis we focus on the design and analysis of secure and efficient protocols of two or more parties in quantum settings.
