Abstract
An Optical Transport Network (OTN) frame comprises an optical channel payload unit that is divided into a plurality of timeslots. This OTN frame is received at a transmitter and the timeslots are grouped into blocks of timeslots. Two or more blocks of timeslots are selected for encryption and are encrypted/authenticated in parallel to generate an encrypted OTN frame in which only certain blocks of timeslots are encrypted.
