- 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...

- 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...
