Design And Implementation Of Large-scale Logistics Information System Security Authentication Subsystem

In the age of e-business, the expansion of the trade scope of the enterprise causes the boom of the logistics, which supports the development of e-business. Yet the construction and application of the information system is the main content of modern logistics. In the construction of logistics information system, it is essential to guarantee the security of such system information as sorting and settlement of account, payment netgate, and the storage of important data, as well as the security of transmission of the important client information. CA certification, which is of prospect and profit, has such functions as online information encryption, decryption and digital signature and the employment of CA certification is compulsory for the security of e-business.In this article there is a discussion of the demand of security certification in the different phases of construction of large-scale logistics information system, such as acceptance of business, storage, allocation, transportation, expense, clients management; then, it is the discussion of the basic principles of modern cryptography, which is the theoretic bases of subsystem of security certification; and then, according to the comparison of three different certification systems, it shows the preference of CPCA certification system in terms of characteristics of large-scale logistics information system concerned; finally, it is the design and actualization of the security certification subsystem. Based on the management and dynamic allocation system of e-business logistics developed for Guangdong Postal Service, this research is about the application of identity certification, transmission of encrypted data, management of privilege and password, management of digital signature and security maintenance through the employment of CPCA.
