Application of these policies to the AICCP for more than one year proves the effectiveness of the data exchange practice between the AICCP and enterprise Intranet.展开更多

文摘To meet the actual requirements of an automotive industry chain collaboration platform （AICCP）, this paper offers several simple but effective security policies based upon the traditional security mechanism of data transfer, including user ID verification with SOAP （simple object access protocol）, header, SOAP message encryption with SOAP extension and XML （extensible markup language） file encryption and decryption. Application of these policies to the AICCP for more than one year proves the effectiveness of the data exchange practice between the AICCP and enterprise Intranet.
