<p>An encryption code and at least one key are provided to a secure transmission device, via an external keying device (100) and stored in a first volatile memory (102). An encrypted representation of the at least one key, based on the encryption code and the at least one key, is generated and stored in a non-volatile memory (103). Upon power down of the secure transmission device, the encryption code is stored in a second volatile memory (106) and the at least one key and encryption code stored in the first volatile memory (102) are erased.</p> |
