摘要: Analysis of authenticity digital certificates includes. Initial information pertaining to digital certificates is collected from diverse information sources. For each of the digital certificates the initial information includes intrinsic parameter data from among contents of the digital certificate and extrinsic parameter data pertaining to the digital certificate and comprising static data not contained in the contents of the digital certificate. Selected parameter data is stored and analyzed to determine a measure of suspiciousness for each of the digital certificates. If necessary, circumstantial data based on actual usage of one or more of the digital certificates are collected. The initial data and supplemental data are compared against a set of decision criteria that define fraudulent activity, and a determination of authenticity of each of the digital certificates is made.
