基于社会智能的网络信息流安全环模型

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．

A Closed Security-Ring Model for Network Information Flow Based on Social Intelligence

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.
