COMMUNICATION MANAGING TABLE TRANSFER SYSTEM AND MANAGING DEVICE, CIPHERING DEVICE, AND COMMUNICATION MANAGING TABLE TRANSFER METHOD

摘要

The present invention relates to a communication management table transfer system including plural encryptors mutually connected through the Internet and a manager which manages the communication management table used for the communication among the plural encryptors. The invention aims to improve security and performance of the communication. On receiving a communication management table version from an encryptor 11 (S301), a manager 36 compares the received communication management table version with the communication management table version stored in a communication management table version memory 2005 of the manager side by using a communication management table checker 2006. The manager 36 transfers the communication management table to the encryptor 11 only when the mismatch is found (S104). <IMAGE>
