Cipher data communications apparatus.

摘要

A facsimile apparatus having a function to perform cipher communication by using a cipher key. In this facsimile apparatus, a received cipher data is stored in a memory (4) at first. In outputting the received cipher data stored in the memory (4), when a cipher key used for the received cipher data stored in the memory (4) coincides with a cipher key set at the time of the output, the received cipher data is deciphered and outputted. When the cipher keys do not coincide with each other, the received cipher data stored in the memory (4) is not erased but left in the memory (4). However, a data specified by a command based on an operation of an operation unit can be erased from the memory (4). <IMAGE>
