Abstract:

Proxy blind signature was applied to the electronic paying system, electronic voting system ,mobile agent system ,the security of the Internet,and etc. A quantum proxy weak blind signature scheme is presented based on the correlation of EPR (Einstein–Padolsky–Rosen) pairs and controlled teleportation. Compared the traditional proxy blind signature schemes based on computing complexity, the scheme uses the physical characteristics of quantum mechanics to implement message blinding, signature and verification, so it could guarantee not only the unconditionally security of the scheme but also the anonymity of the message owner.

Key words: quantum information, quantum signature, proxy signature, weak blind signature, controlled quantum teleportion
