Abstract:

网构软件是一种面向网络环境的新型软件形态,其构建依赖于对开放协同环境中各种异构的、自治的软件服务实体间的有效协同.由于网络环境不可控和不确定性,对网构软件运行时刻的可信保障提出了严峻要求,针对这一要求,提出了一种面向网构软件的信任驱动模型.该模型以软件实体为基本管理对象,以可信联盟的方式建立一种具有认知能力的柔性网构软件架构,在保证局部认知能力同时,具有全局预警和防御的能力.同时,为满足网构软件可扩展性和在线演化性需求,对模型功能单元及规则策略集合进行可扩展性设计,使模型具有较强的适应性,且随时间地推移具有良好的进化能力.实验证明,模型能够有效支持信任管理及信任关系的在线演化,有助于解决开放环境下网构软件的可信性问题.
