Abstract:
1. A method for synchronizing encryption and decryption of a data frame in a communication network, the method comprising: encrypting a first data frame based on a first unique code in a first communication device, said first unique code being derived from a first sequential code; encapsulating said first encrypted data frame in a first transport frame, said first transport frame comprising a first portion and a second portion of said first sequential code; encrypting a second data frame based on a second unique code in the first communication device, said second unique code being derived from a second sequential code; encapsulating said second encrypted data frame in a second transport frame, said second transport frame comprising a first portion and a second portion of said second sequential code; and transmitting said first transport frame and said second transport frame to a second communication device, wherein said first portion of said first sequential code and said first portion of said second sequential code identify the same relative portions of said first and second sequential codes, and said second portion of said second sequential code represents a successive relative portion with respect to said second portion of said first sequential code.
