Research On Identity-Based Cryptography Electronic Business Security Architecture

The traditional system of Electronic Business security guarantees the Electronic Business's confidentiality, integrity,usability,the authentication and undeniable mainly through entity authentication,digital signature,encryption by using the PKI/CA system.However,because of the complexity of the digital certificates management in PKI/CA system,it is unsuitable for real-time online exchanges and so on,therefore, it is necessary to improve the existing PKI/CA system.In Identity-Based Cryptography(IBC)of Public Key Cryptography System(IB-PKCS)no longer needed in the digital certificate,the user' public key is its identity(or identity information into the draw),greatly simplifies the traditional The PKI/CA system with the heaviest burden of key management.This article will replace the traditional public key cryptography system for identity-based cryptography of public key cryptography system,the WS-Security specifications expansion by the identity-based Web services security(IB-WSS) Architecture.To use bilinear pairings technology,this paper achieves the Identity-Based Public Key Cryptography System(IB-PKCS)in infrastructure:identity-based encryption(IBE);identitybased digital signature(IBS);identity-based key agreement (IBAKA);Combined with existed XML digital signature,XML encryption,Web Services Security standard Identity-Based Cryptography of the public key infrastructure(IB-PKI),build a complete identity-based cryptography Electronic Business security system.Finally,the security system prototype in a securities trading system.
