Abstract

Through the use of secure email, it is possible that a user will receive an encrypted message that contains an attachment. However, in the current mobile device architecture, attachment handling is provided by the attachment server and not on the handheld itself. This invention would solve this problem by providing the ability for the handheld to download a temporary attachment decoder or distiller that would enable the handheld to directly decrypt the attachment on the handheld. This allows the user to retain the security of the message and the attachment (no requirement to send the session key or other information to the attachment server). It also allows the user to read attachments directly on the handheld without having to preload the expected attachment handlers when loading the handheld software. By dynamically downloading a temporary attachment handler it allows the device to perform a desired action by the user without paying the price for application space throughout the use of the handheld. As well, third-party application developers could use the attachnment distiller with an appropriate framework to develop these dynamic handlers for handheld use.
