Research On Electronic Payment Protocol Based On Quantum Theory

Electronic payment is a very important business activity.Its convenience has brought us great convenience.Due to the continuous interaction of various information,protecting user privacy in the payment process has become a very important content.Quantum payment is quantum A major branch of cryptographic research,its security is based on the physical properties of quantum itself,and can effectively resist quantum computing attacks.Using quantum theory to design payment protocols is an effective way to protect user privacy.This article uses local areas.Indistinguishable orthogonal direct product state and single photon The following two quantum payment protocols are designed,as follows:In the research of quantum payment based on local indistinguishable orthogonal direct product states,this paper uses a special type of local indistinguishable orthogonal direct product states(X-LIOP)to design a new type of quantum payment protocol.In this protocol,the purchase information is encoded as a quantum sequence of the orthogonal direct product state,and the different particles of the orthogonal direct product state are transmitted separately.Since the attacker can only get part of the particles and cannot get the entire the orthogonal direct product state,the protocol designed in this paper meets the requirements of blindness,unforgeability,and undeniability,and is easy to implement in practice.In the study of single-photon-based quantum payment,this paper proposes a single-photon-based quantum payment scheme.In this scheme,the buyer's purchase information is encoded into a specific single-photon sequence,and the bank is encrypted Do not know the buyer's purchase information.The above agreement satisfies the blindness,can effectively prevent external attackers and sellers from forging purchase information,and can prevent buyers from denying purchase information and payment amount.
