Abstract: This paper proposes a secure authentication protocol in a new direction with group signature based Quantum cryptography for a networked organization. The group signature setting has a group with copious members and one manager. The proposed protocol uses a trusted centre TC generates a large heap of public/private key pairs. Every member of the group has a different list of unique private keys which is distributed by TC to sign a document. The keys are immunable using quantum key distribution protocol which acquires the properties of quantum mechanics.
Keywords: Group signature, public/private key, quantum cryptography, quantum key distribution protocol QKDP, Trusted Center TC.
