Abstract
A network of storage units has a data path, which is at least a portion of the network. The network also has a dynamic time-varying or cycle-varying code generation unit and a code comparator unit that together make up an unlock signal generation unit; and a gateway storage unit. If the gateway storage unit does not store an unlock signal or the unlock signal generation unit does not generate and transmit an unlock signal, the gateway storage unit does not insert a data path segment in the data path. If the unlock signal generation unit is operated such that it generates an unlock signal, and it transmits that unlock signal to a gateway storage unit, and the gateway storage unit stores the unlock signal value, then the gateway storage unit inserts a data path segment into the data path.
