Abstract:
1. A system for processing electronic messages, the system comprising a base computer, the base computer comprising: a first memory for storing one or more digital certificates issued by a certificate authority for use in at least one of decrypting secure electronic messages, encrypting secure electronic messages, or signing secure electronic messages; and program logic operable to automatically identify at least one digital certificate of the one or more digital certificates in the first memory for downloading to a second memory at a mobile communications device, wherein the at least one digital certificate is identified based on detection of new cryptographic keys at the base computer, and digital certificates stored in the first memory that correspond to the new cryptographic keys; wherein said new cryptographic keys are determined by comparing a history list, stored at the base computer, of previously available cryptographic keys with a current list, stored at the base computer, of cryptographic keys; wherein said program logic is configured to automatically download said identified at least one digital certificate to said second memory at the mobile communications device; and wherein said program logic is invoked via a cryptographic key synchronization utility running on said base computer.
