Arbitrated Proxy Signature Scheme Based on Quantum Cryptography
Proxy signature is a special signature which provided the signer can delegate his signing capability to others. The proxy signature provides that the original signer can delegate his signing permission to a proxy signer, and the proxy signer can replace the original signer to sign the message. In this paper, we propose a proxy signature scheme based on ideas from classical proxy signature schem...
متن کاملRemarks on One Arbitrated Quantum-signature Scheme
Zeng and Keitel proposed an arbitrated quantum signature scheme In 2002. Recently, Curty and Lütkenhaus pointed out that the protocol is not operationally specified. In a reply, Zeng gave more details of the scheme. The author also claimed that the scheme is suitable for unknown messages. In this letter, we remark that the invented scenario in the original scheme is artificial. This is because ...
متن کاملAn Arbitrated Quantum Signature Scheme Based on Chaotic Quantum Encryption Algorithm
An arbitrated quantum signature (AQS) scheme is demonstrated via the improved quantum chaotic encryption algorithm with the quantum one-time pad based on chaotic operation string. In this scheme, the signatory signs the message and the receiver verifies the signature's validity with the aid of the arbitrator who plays a crucial role when a dispute arises. Analysis shows that the signature can n...
متن کاملAn efficient and provably secure arbitrated quantum signature scheme
Two arbitrated quantum signature schemes, one with message recovery and the other with appendix, are proposed. The two proposed schemes need not prepare quantum entanglement states, do not require comparing qubits, only require von Neumann measurement, and have a significant property that both the signatory and the receiver can share and use a long-term secret key with the arbitrator by utilizi...
متن کاملDigital Signature based Proxy Multi-Signature Scheme
A Proxy signature scheme enables a proxy signer to sign a message on behalf of the original signer. In this paper, we propose ECDLP based solution for chen et. al [1] scheme. We describe efficient and secure Proxy multi signature scheme that satisfy all the proxy requirements and require only elliptic curve multiplication and elliptic curve addition which needs less computation overhead compare...
