Improvement of a quantum proxy blind signature scheme is proposed in this paper. Six-qubit entangled state functions as quantum channel. In our scheme, a trust party Trent is introduced so as to avoid David’s dishonest behavior. The receiver David verifies the signature with the help of Trent in our scheme. The scheme uses the physical characteristics of quantum mechanics to implement message blinding, delegation, signature and verification. Security analysis proves that our scheme has the properties of undeniability, unforgeability, anonymity and can resist some common attacks. 相似文献

We present a new protocol for quantum sealed-bid auction with a set of ordered cluster states. The bidder’s biding information can be transmitted to the scrutineer Trent with the help of the auctioneer Charlie. Trent’s supervision in the whole auction process can ensure trust among participants and avoid dispute. Our scheme uses the physical characteristics of quantum mechanics to achieve auction. In addition, we also analyze the security of the protocol, and the scheme is proved to be secure against attacks. 相似文献

In this paper, a very efficient and secure multi-proxy multi-blind-signature scheme is proposed which is based on controlled quantum teleportation. Genuine six-qubit entangled state functions as quantum channel. The scheme uses the physical characteristics of quantum mechanics to guarantee its unforgeability, undeniability, blindness and unconditional security. 相似文献

A practical E-payment protocol is presented in this paper. It is based on quantum multi-proxy blind signature. Adopting the techniques of quantum key distribution, one-time pad and quantum multi-proxy blind signature, our E-payment system could protect user's anonymity as the traditional E-payment systems do, and also have unconditional security, which the classical E-payment systems can not provide. Furthermore, compared with the existing quantum E-payment systems, this practical system could not only support mobile E-payment transactions but also inter-bank transactions. 相似文献

In this paper, a multi-proxy blind signature scheme based on controlled quantum teleportation is proposed. Entangled four-qubit Cluster state functions as quantum channel, which needs less resource to complete the quantum multi-proxy blind signature. The scheme uses the physical characteristics of quantum mechanics to guarantee its blindness, unforgeability, and undeniability. The eavesdropping check is used to ensure the security. Our scheme has a foreseeable application to the E-business, E-governments, and etc. 相似文献

In this paper, a secure and economic multiparty english auction protocol using the single photons as message carrier of bids is proposed. In order to achieve unconditional security, fairness, undeniability and so on, we adopt the decoy photon checking technique and quantum encryption algorithm. Analysis result shows that our protocol satisfies all the characteristics of traditional english auction, meanwhile, it can resist malicious attacks. 相似文献
