Key distribution protocol for file transfer in the local area network

摘要

A cryptographic communications apparatus and method for use with a first terminal, a file server, a key distribution center and a communications channel. The method is made simple by using classical-key-encryption algorithms for electronic generation of session keys. The terminal is verified at a key distribution center, using time stamp and secret identification numbers. Each path is encrypted, with each encrypted message decoded at the key distribution center and file server.
