Abstract:
1. A method to limit access to information using a fibre channel arbitrated loop system, comprising the steps of: inspecting an incoming data frame comprising serial data; determining the source address and the destination address included in said incoming data frame; providing permitted address information; providing an IDLE character generator; providing a deserializer, providing a decoder; providing said serial data to said deserializer; converting said serial data to a plurality of ten bit parallel words; directing said plurality of parallel words to said decoder; packaging said plurality of words in groups of four as 32-bit words comprising a parity bit for each byte; placing said parallel data into a regulator; providing a trigger circuit, wherein said trigger circuit is in communication with said regulator; providing an encoder, wherein said encoder is in communication with said regulator; comparing said parallel data to said permitted address information; operative if said incoming data frame is addressed to an unconfigured source/destination addressed pair, replacing said incoming data frame with IDLE characters; operative if said incoming data frame is not addressed to an unconfigured source/destination addressed pair, triggering said regulator to pass said parallel data to said encoder; converting said plurality of parallel words to said serial data; and passing said serial data to said destination address.
