ID-BASED ENCRYPTION AND SIGNATURE METHOD AND TERMINAL

摘要

The present invention relates to a terminal including an ID-based processing module that uses the ID of a transmitter or the ID of a receiver, as part of or an extension of the file name of a file that the transmitter transmits to the receiver. By doing so, a user can recognize a secure file with the naked eye, and a connection program can be designated to an extension. Therefore, when a user decodes or verifies a file, the designated program may be easily used.
