The way that Web security has been managed by the government will influence user's satisfaction and intention toward using web and trust in the government. The purpose of this research is to link user's satisfaction with web security in eGovernment and trust in government; that is, it aims to study the relationships among user's satisfaction, trust and government. The main question is "does user's satisfaction of web security in eGovernment influence user's trust in the government?" The research explores the status quo of web security in government, and studies user's satisfaction of web security which influences user's trust in the government. The research focuses on the investigation of users' satisfaction and trust of web security via the method of questionnaires applied the structural equation modeling (SEM) to analyze users' trust in the use of web security. The statistic method is applied LISREL 8.54 to analyze questionnaires' data. This research shows that the precursors of user intent to trust web security are multidimensional (i.e., ease of use, perceived usefulness, attitude and satisfaction) and identifies their critical influences on realizing government web security. These two dimensions are interwoven, and one must not focus exclusively on any single factor in assessing overall intention toward trust eGovernment.
