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.
