Mutually secure multi-tenant optical data network and method

摘要

A digital optical data network system securely interfaces data traffic between multiple carriers (114,116,118) and multiple end user tenants (102,104,106) of a site such as an office building (100) by accepting multiple carrier data lines (120,122,124) at a common specialized headend (128) for the building, encrypting/decrypting the traffic at the headend, and feeding (130,132,134) the same encrypted optical data feed to each of the multiple private tenants. Each tenant has a specialized encrypting/decrypting optical network unit for extracting and injecting only its data to/from the feed.

主权项

1. A digital data network communication method comprises:
accepting a plurality of private data streams serving a plurality of private tenants; encrypting each of said streams; aggregating said encrypted streams into a combined encrypted data feed; optically routing said encrypted data feed to at least two of said plurality of private tenants; extracting from said encrypted data feed a first one of said private data streams; wherein said extracting comprises:
partially decrypting said encrypted feed.
