摘要
文中讨论多主体系统中的安全性要求和实现方法,为了对付非法入侵者,多主体系统必须在安全的加密信道上运行,并提供多层次的检查机制,以满足分布式应用的要求,文中提出基于RSA和Rabin算法的加密信道,提供底层的签名和加密服务,并构造高层的权限控制机制DSM.在DSM中提出一种混合的权限检查方案,主体凭借其身份类别可以访问一类缺省的主体的服务,以及利用主体ID进行访问.
The requirement and implementation of data security in multi\|agent systems are discussed in the paper.To make itself intruder\|proof,a multi\|agent system must run on encrypted channel and provide the mechanism of multi\|layer authentication.Here presented is a method to ensure the security,which first provides low level signature and data encryption based on RSA algorithms,and then constructs a high level distributed security mechanism (DSM).In DSM,the approach to access control is put forward.The agent can access the default services of another agent by its identification for flexible security configuration.
