基于XML安全规范的多Agent细粒度安全通信模型

Fine-grained Security Model of Multi-agent Communication with XML Specifications

为了确保Agent通信过程中消息的完整性、可认证性、以及保密性,将XML安全规范与Agent通信相结合,提出了一个细粒度的安全通信模型.在该模型中,基于XKMS标准对数字证书进行管理,实现了通信双方身份的认证.同时,采用XML加密与签名机制,在通信过程中只对敏感信息进行加密或数字签名,而保留其它相关信息为明文,提高了系统的效率降低了通信带宽.

The communication security of MAS is an important issue in practice. In order to ensure information integrity, authentication, and confidentiality, this paper presents a fine-grained security model for MAS communication with XML security specifications. In this model, entity identity is authenticated by digital certificate management based on XKMS. Meanwhile, through adopting XML encryption and XML signature mechanism, the model only encrypts or signs portions of information to improve the system efficiency and decreases bandwidth in communication.
