Grids support dynamically evolving collections of resources and users, usually spanning multiple administrative domains. However, how to establish trust among strange domains without prior relationship and common security domain posed much difficulty for these resource sharing. Automated trust negotiation （ATN） is an approach which establishes trust between strangers through the bilateral, iterative disclosure of digital credentials. In this paper, an ATN model in Grid Environment, policy sets, negotiation strategy and negotiation protocol are presented. The main process of ATN includes: establishment of policy sets, converting policy sets into disclosure graph which improves Method Yu, reducing disclosure graph to disclosure tree, converting disclosure tree into disclosure sequence, and establishment of negotiation protocol.

The problem of image denoising is a primary operation in the stage of image *** recent years,combining the image filter with grey system theory,some scholars present an adaptive added-weigh mean filter algorithm which is a optimizing process to obtain the value of weigh decided by comparing the similarity between the grey levels of sample pixels in the filter window and the mean grey levels of pixels in the window based on the grey relational *** with the traditional mean filter,it has achieved certain progress. However,because of the defects of the algorithm of its own, when the noise density reaches a certain level,the processing results are *** main part unreasonable is that when filtering the image we do not make a clear distinction between the noise points and normal ones,which will inevitably lead to the edge blurred *** this paper, we first use a new detector to distinguish between the noise and normal *** we just do filter operation to the pixels which have been sentenced to noise points using an improved filter algorithm based on grey relational ***,the experimental results demonstrate that the algorithm improved is significantly better than the classical mean filter,median filter and the traditional image filter algorithm based on the grey relational analysis.
