| Abstract: | The construction and validation of cross-certificate chain usually need plenty of time, which limits its extensive application. Based on a hybrid trust model supporting cross-certification, this paper puts forward two optimizing algorithms about adding path validation into path construction, which support cross-certificate forward path construction on the searching basis of depth first and adjusting strategy tree and sequence validation in the path validation. By these methods, the efficiency to the path construction and the path validation and the availability of cross-certificate are improved. |
