- Ethernet Passive Optical Network (EPON): A Tutorial
- A Passive Optical Network PON is a single, shared optical fiber that uses inexpensive optical splitters to divide the single fiber into separate strands feeding individual subscribers. PONS are called "Passive" because, other than at the CO and subscriber endpoints, there are no active electronics within the access network. Using...

- Securing Passive Optical Networks Against Signal Injection Attacks
- Any access network is subject to various intrusions, caused by intended attacks or by unintended failures (employed here analogously to "Attacks"). Such attacks can target security items, e.g., information reaches a specific port to which it was not intended, or attacks may concern network accessibility, i.e., the possibility for a...

- Insecurity in ATM-Based Passive Optical Networks
- This paper considers the security of an ITU standard for ATM-based passive optical networks. First, it shows that the standard's encryption algorithm, called churning, has an effective 8-bit key length and thus is trivial to break with exhaustive keysearch. Second, it shows that the authentication mechanisms have significant weaknesses. The...
