Abstract:
1. A method of authentication of an electronic device, comprising: obtaining a set of authentication parameters for an X.509 certificate from a memory on the electronic device; prioritizing the X.509 certificate authentication parameters into: express-parameters defining one or more express check points that include consistently reliable parameters from a static source, and post-parameters defining one or more post-check points that includes time/date fields that are unreliable, said prioritizing performed by a processor on the electronic device; authenticating each express check points; upon successful authentication of each express check point, determining whether a post-parameter is reliable; and if the post-parameter relating to time/date setting is reliable, authenticating the post-check point corresponding to the post-parameter, said authenticating performed by the processor on the device; wherein an authentication failure of the post-parameter is avoided, thereby preventing a re-setting of the entire authentication process of the device, including re-authentication of each express check points.
