Abstract

Ethernet Optical Passive Networks (EPONs), defined as low cost access networks, combine Ethernet technology with an optical fiber infrastructure to deliver voice, video and data services from a Central Office (CO) to end-users Since all data in the downstream is broadcasted, it is susceptible to be eavesdropped by a malicious user, which can use it to try Theft of Service (ToS) through masquerading techniques These threats remain present when encryption is applied to EPON frame payloads In order to avoid user profile inference through data mining techniques, a method for encryption of the preamble of the data units is proposed in this paper and a short description of its operations is presented This new encryption mechanism assures that any two EPON frames are always transmitted with different and uncorrelated preambles.
