基于匹配策略的安全协议重构分析

Establishment of reconfigurable security protocols based on matching policies

可重构安全协议对提高安全系统的灵活性和适应能力具有重要意义,它可根据具体上下文环境进行配置、移植,极大增强了系统的安全性,目前基于软件构件的协议重构方法无法满足安全协议对安全性和计算性的特殊要求。针对安全协议的安全性和高密度计算特性,提出了一种针对现有资源选择重构元的解决方法,给出协议可重构元匹配和基于Qo S的重构元质量满意度的协议重构选择算法,使系统可以尽快按照重构协议需求选择满意的可重构元。通过实例说明该方法的执行过程,应用结果表明该方法能够有效提高重构效率和重构准确度。

Capable of being configured and ported according to specific contexts,the reconfigurable security protocols can greatly enhance system security,and therefore are of great significance to the flexibility and adaptability of security system.However,up till now,all reconfigurable protocols have been based on software components,thus fail to meet the special requirements of security protocols on security and computability. In consideration of the characteristics of security and high-density,this paper put forward a new solution to find quickly the reconfigurable protocol units according to the existing resources,which could offer the Qo S-based algorithm of the suitable reconfigurable protocols and allowed the system to choose the desirable reconfigurable components in accordance to its needs. Through the illustration of the executive process of this new method,the result shows that this algorithm can effectively improve the reconfiguration efficiency and accuracy.
