METHOD AND SYSTEM FOR THE PROTECTED DISTRIBUTION OF NETWORK FILES

摘要

A system for authenticating two peers within an authentication protocol. The peers are associated with a shared secret common to the peers and an identical randomization agorithm that utilizes a pseudorandom generator. In response to a command received from a challenging peer from among a challenging peer from among the two peers, the other peer (constituting a challenged peer), applying the randomization algorithm seeded by the shared secret so as to obtain one or more outputs. The challenged peer applying transformation to the output and to data of packet so as to obtain a response. A transmitter transmitting the packet and the response to the challenging peer. The challenging peer applying the algorithm and compares the so-obtained response to that received from the challenged peer and in the case of match the challenged peer is authenticated.
