The method of secure data exchange using Flash RAM media

This document describes the method for secure transfer of flies stored in Flash RAM through unsecured transport channel (e.g.: courier) between users. In this method the sender of the file specifies the recipient and the recipient knows who is the sender of the file. The idea of a solution that uses symmetric and asymmetric encryption is described. The following procedures are presented: creating protected file (encryption), generating signatures for that file and reading (decryption) the file.
