摘要
基于人类的社会智能特征,提出了一种网络信息流安全环模型.该模型分4个层次控制网络信息流的动态安全:安全入口层负责用户的身份验证和信息流的安全封装;社会智能层赋予信息流自我感应、自我保护、自我调控的行为能力;事务层实现商业事务的提交、处理、回滚,提供实时保护和在线恢复机制;TCP/IP安全协议层则保障网络信息流的安全传输.这4个层次协同运作,构建了不同等级的安全环.通过数学模型的建立和论证,证明该模型可以有效地保障网络信息流的动态安全,为商业事务的整体安全提供了一种可行的解决方案.
This paper puts forward a security-ring model for network information flow based on human social intelligence. The model controls the dynamic security of network information flow on four layers： Security entrance layer requires user authentication and encapsulates security information flow; Social intelligence layer makes information flow to have the ability of self-sensing self-protecting and self-adjusting; Business layer carries out business logic in forms of transactions which can be submitted, processed and roll back, in order to provide real-time protecting and online recovering; TCP/IP security layer ensures security communication for information flow. These four security layers corporately run to build different grades of security-rings. By establishing mathematics model and reasoning, it is verified that the model can effectively guarantee dynamical security of network information flow and provide a feasible method for the whole business security.
