ID-BASED ENCRYPTION AND SIGNATURE METHOD AND TERMINAL

摘要

Provided are an identity (ID)-based encryption and signature method and a terminal that use an ID of a transmitter or a receiver as a part of the filename or the extension of a file transmitted to the receiver by the transmitter. Accordingly, it is possible to enable a user to visually recognize that the file has been provided with security. Also, it is possible to designate an associated program for the extension, and the user can easily decrypt or verify the file through the designated associated program.

主权项

1. A terminal, comprising:
a processor; a storage, accessible to the processor, configured to hold at least part of a file; a transmitter configured to transmit the file to a receiver; and an identity-based (ID-based) processing module, implemented by the processor, and configured to implement at least one pre-transmission file security measure with respect to the file using a component ID of one of the transmitter and the receiver to provide a processed file.
