Quantum Group Proxy Digital Signature based on Quantum Fourier Transform by Using Blinded and Non Blinded Trent
نویسنده
چکیده
In this study, quantum proxy group signature protocol based on the Quantum Fourier Transformation (QFT ) is suggested. In this protocol, QFT is used to share signature with group members. So all proxy group members know only their part of the signature information which are encrypted output of the QFT . This improves the security of the protocol. In addition, the security of the quantum proxy group signature is provided by using reorder QFT output qubits with permutation of the Trent, blinded and non-blinded . The security analysis expresses higher efficiency, effective secret key usage and security of the proposed

In this study, the security of Novel Enhanced Quantum Representation (NEQR) of quantum images are suggested by using the Quantum Fourier Transform (QFT ) with blind trent. In the protocol, QFT and keys are used to share signature with recipients. So all members know only their signature information which are encrypted output of the QFT . This improves the security of the protocol. In addition, ...
متن کاملArbitrated 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...

In this study graphene oxide (GO) was synthesized by using Hummer’s method. Low dimension graphene quantum dot nanoparticles (GQDs) were synthesized using pulse laser irradiation. Fourier Transform-Infrared Spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) spectroscopy and photoluminescence (PL) analysis were applied to study the GQDs characteristic. Scanning electron microscopy illustrated the...
متن کاملA post-quantum proxy signature scheme based on rainbow digital signature
Quantum computers have recently emerged as a threat to the traditional public key cryptosystems based on the difficult problems of integer factoring, discrete logarithm, and elliptic curve, such as RSA, DSA, ElGamal, and ECC. The proxy signature schemes based on these cryptosystems have been threatened at the same time. So it is important to propose efficient and secure proxy signature schemes ...
متن کاملA Step Towards QC Blind Signatures
In this paper we propose a conversion from signature schemes connected to coding theory into blind signature schemes. We give formal security reductions to combinatorial problems not connected to number theory. This is the first blind signature scheme which can not be broken by quantum computers via cryptanalyzing the underlying signature scheme employing Shor’s algorithms. We thus present a st...
