Security verification system based on distributed network transaction

Abstract

The invention provides a security verification system based on distributed network transaction and relates to the field of network transaction security of financial institutions. The security verification system is in remote connection with a payment terminal device of a user and comprises a token generation subsystem, a token management subsystem and a token verification subsystem. The token generation subsystem is used for generating encrypted tokens, and information of each token comprises a serial number, a token key and a digital activation code. The token management subsystem is used for managing token issuing, toke loss reporting or token destroying. The token verification subsystem is used for verifying the payment terminal device of the user. The three subsystems are disposed in a distributed manner, the three subsystems are provided with a same transmission main key inside, remote communication is applied among the different subsystems, and information of the communicated token each time is re-encrypted. By the security verification system, operations such as signature by theft on certificate storage medium by computer Trojan online can be prevented effectively, and security of an online transaction system is guaranteed. In addition, by the use of the distributed structure, expandability is high, and manpower and material resources costs are reduced.

Description

technical field [0001] The invention relates to the field of network transaction security of financial institutions, specifically a distributed-based network transaction security verification system. Background technique [0002] With the rapid development of computer network and information communication technology, computer network technology has been more widely used in financial industry systems. The concept and characteristics of network transaction security The network transaction security in the Internet era is the protection of the hardware, software and data of the computer system, making full use of advanced modern technology and equipment to improve the efficiency of transaction activities, so that the system can continue to work normally, without due to Altered, destroyed or leaked confidential information accidentally or maliciously. According to the statistics of relevant departments in Germany: the transaction cost of a transaction through the bank counter is...
