Application Of XML Secrecy Technique In ERP Development System

With the development of enterprise information, the important part in ERP system: the secrecy, must to be resolved The PKI ( Public Key Infrastructure ) Technique based public key System is a perfect way to realize a secrecy system, it offers support frames of security service and resolves the problem of the distribution of key, is becoming the key part of the whole security system structure.The XML is widely used in various fields for it's following advantage:structure,labeled, and flexible. When the XML comes to be a widespread data encoding format of Web application, many research about the security of XML are developed. Now,the W3C manage the standards of XML security specification. The XML secutity specification proved the ability of element-control, it's make a new style of encryption and sign.Because of the limits of many conditions, at present, PKI which used in enterprise environment is still rare, EOS secrecy -system is the procedure that developed on the basis of Microsoft's Security class library by author. It realizes main function of typical secrity system,which has certificate requisition,cerfificate signature, certificate revocation, cerfificate inquire, private key recovery etc, can meet the needs of security for enterprise. EOS secrecy -system is a sub-system of EOS AUTOERP, it make the AUTOERP development system have the ability of develop a ERP including PKI, and the engineers can use it to create a PKI frames easily. This secrecy system merge the principle of PKI and the element-control ability of XML, and public it with WEBServises , has the ability of realize a safe ERP system with limited cost., and even more, it is independent of development language.In this dissertation, the Author introduce foundation of cryptography, expound the the theory of PKI and the PKI structure, and the technique of XML , WEBServices. On this basis , analyze the characteristics of enterprise , and give the policy of security service . These policy are all supported by XML security technique,and to resolve the problems with simple way. Finally, explain the main fraims andmain module of security-system briefly.
