摘要
当前XML加密普遍采用对称算法和非对称算法组合的"二次"加密方式,并且密钥交换依赖传统PKI体制,存在加/解密过程复杂等缺陷。通过对XML加密规范和IBE体制以及双线性映射算法的研究,提出采用IBE密钥机制和双线性映射算法实现XML加密的数据安全交换方案,对相应的XML数据交换过程和XML加密文件结构进行了设计,对该方式的XML加密关键环节实现方式做了具体阐述。作为一种新型XML加密方案,在保证数据安全交换的同时,简化了XML加密过程,并克服了传统PKI的缺陷。
XML encryption adopt combined way of symmetric encryption algorithm and asymmetric encryption algorithms presently, and rely on traditional PKI system , so has some limitation such as the process of XML encryption is complicated. By the research of XML encryption syntax and processing , this paper proposes a data exchanging resolution safely of XML encryption by IBE key system and weil pairing algorithm, then the process of XML encryption and the configuration of XML document based on IBE are devised, finally, the relative key technologies are researched and described in detail. Be a new scheme of XML encryption ,it can predigest the process of XML encryption and overcome the limitation of traditional PKI system While ensure safety of data.
