With the rapid development of electronic commerce, payment is becoming the focus problem of electronic commerce. Electronic cash has become the ideal method of electronic payment for it is able to realize fair, secure, effect electronic transacts. Along with electronic commerce development, electronic cash payment systems are also gradually developing. However, most electronic cashes are facing the security issues. Moreover, the amount of money each electronic cash card contains is fixed at issuance and is available only within a specified system. The key technology is digital signature technology, including blind signature, group signature, and ring signature. The paper researches the security problems of electronic cash in information safety and e-commerce, and discusses the electronic payment and the security problem, which is regarded as the foundation of electronic commerce. The main factors are given that causes security problems of electronic payment, and suggests corresponding precautionary measures.

AbstractProxy signature and group signature are two basic cryptographic primitives. Due to their valuable characteristics, many schemes have been put forward independently and they have been applied in many practical scenarios up to the present. However, with the development of electronic commerce, many special requirements come into being. In this article, we put forward the concept of group–proxy signature, which integrates the merits of proxy signature and group signature for the first time. We also demonstrate how to apply our scheme to construct an electronic cash system. The space, time, and communication complexities of the relevant parameters and processing procedures are independent of group size. Our demonstration of the concrete group–proxy signature scheme shows that the concepts brought forward by us are sure to elicit much consideration in the future.

As the core of intelligent manufacturing, CPS has serious security issues, especially for the communication security of its terminal M2M. In this paper, blockchain technology is introduced to address such a security problem of communications between different types of machines in CPS. According to the principles of blockchain technology, we design a blockchain for secure M2M communications. As a communication system of M2M consists of public network areas, equipment areas and private areas, we design a sophisticated blockchain structure between the public area and private area. For validating our design, we take cotton spinning production as a case study to demonstrate our solution to M2M communication problems under the CPS framework.

Electronic Payment System

An electronic cash system allows the exchange of digital coins with value assured by the bank’s signature and with concealed user identity. In an electronic cash system, a user can withdraw coins from the bank and then spends each coin anonymously and unlinkably. In this paper we propose a secure and efficient off-line electronic payment system based on bilinear pairings and group signature schemes. The anonymity of the customer is revocable by a trustee in case of a dispute. Because the amount of communication in the payment protocol is about 480 bits, the proposed off-line electronic payment system can be used in wireless networks with limited bandwidth.

Electronic commerce system is now developing at a huge speed, whose final objective is to electronize every phase of commercial activity. Electronic payment is the heart of electronic commerce. Along with electronic commerce development, electronic cash payment systems are also developing. How to achieve safe electronic transactions is the key to the development of electronic cash payment systems. There are two kinds of electronic cash system, on-line and off-line. As the security and effective electronic payment system has become an important part of electronic commerce, according to the new character of cloud computing, it can solve the problems that the electronic cash systems exist leakage of privacy, non-standard transactions and high cost in the traditional network. The paper describes the types of electronic payment and discusses the electronic cash payment safety based on cloud computing. The presented solution can reduce the hardware and software systems cost, particularly for the current electronic commerce security, with efficient and convenient interactive response to the trend.

With the rapid development and widespread applications of Internet of Things (IoT) systems, the corresponding security issues are getting more and more serious. This paper proposes a multistage asymmetric information attack and defense model (MAIAD) for IoT systems. Under the premise of asymmetric information, MAIAD extends the single-stage game model with dynamic and evolutionary game theory. By quantifying the benefits for both the attack and defense, MAIAD can determine the optimal defense strategy for IoT systems. Simulation results show that the model can select the optimal security defense strategy for various IoT systems.
