中文摘要：

为格子身份的一个新认证算法信任了由硬件无限的计算被介绍；信任的根作为一个图象数据被做。当它图象根的特征完全在规模空格进程从另外的实体特征数据库与那被匹配时，格子实体在软平台被信任。认出并且检测稳定的图象根特征，非同类的线性可扩充的规模空间被建议。集中于在不同类的 Gaussian 函数术语和热散开的空格进化的规模参数之间的关系同类的方程，三个空格进化操作符被构造到准确并且从图象根标记特征。分析和确认被继续新规模空间，操作员和为格子实体证明作决定的核心。

英文摘要：

A new authentication algorithm for grid identity trusted computing unlimited by hardware is presented;the trusted root is made as an image data.The grid entity is trusted in the soft platform when its feature of image root is entirely matched with that from the other entities＇ feature database in a scale space process.To recognize and detect the stable image root feature,the non-homogeneous linear expandable scale space is proposed.Focusing on relations between the scale parameter of the inhomogeneous Gaussian function terms and the space evolution of thermal diffusion homogeneous equations,three space evolution operators are constructed to exact and mark the feature from image root.Analysis and verification are carried on the new scale space,operators and the core of making decisions for grid entities certifications.
