Research On The Security Supporting Platform Integrated With Trusted 2D Barcode And PKI For Application System

The security supporting platform for application system provides security features to the applications with programming interface, witch makes the application systems shield the complexity of the implementation details of security technology, what’s more,that makes vital significance to reduce developing difficulty of security technology for application systems. In this paper, consider with the demand of practical engineering application system for trusted 2D barcode and the function of PKI system, this paper explores the security supporting platform integrated with trusted 2D barcode and PKI for application system in-depth, the main work is as follows:(1) Puts forward the scheme of a trusted 2D barcode with hidden signature. This paper presents a solution of encoding signature in redundant filling area of a 2D barcode. By introducing the concept of the coding capacity, while encoding isoquant information under the same conditions, the 2D barcode with greater version will get a certain amount of redundant filling area,what’s more, encoding signature in the filling area will be possible. This paper provides the hidden signature and the signature verification algorithm in a 2D barcode.(2) Designs the security supporting platform integrated with trusted 2D barcode and PKI for application system. This platform includes the function modules of trusted 2D barcode Web service CUMQRCode and the programming interface CUMSSOAPI,2D barcode Windows service CUMQRCodeSvc and the programming interface CUMQRCodeSvcAPI, USBKey secure login Web services CUMSSO and the programming interface CUMSSOAPI, USBKey secure login Windows services CUMSSOSvc and the programming interface CUMSSOSvcAPI, USBKey user management site CUMSSOWeb. what’s more,the platform services the application systems which adopt the different development environment and programming language,such as dot NET, Java, Delphi and so on,with trusted 2D barcode and USBKey secure login function programming interface,and it will be very convenient to achieve the corresponding security function for the application systems.(3) Realizes the security supporting platform integrated with trusted 2D barcode and PKI for application system, and integrated the security supporting platform in a centralized procurement drug trading platform. The successfully applying shows that:the trusted 2D barcode with hidden signature can be implemented in general equipments,what’s more, while securing the 2D barcode, the trust 2D barcode technology will not affect the serviceability of 2D barcodes;By applying the security supporting platform API,the difficulty of the safety function development of the application systems is reduced effectively,and the efficiency of the development and maintenance of application system are improved,the cost of development and maintenance will be reduced.
