TDM-PON Security Issues: Upstream Encryption is Needed

Abstract: TDM-PONs (E/B/GPON) present several security issues that can easily be exploited by malicious users. We summarize these issues and present experimental results to demonstrate that, in particular, upstream encryption is required to prevent eavesdropping.

“…In the analysis, 40 Gb/s data rate, 128 sub-carriers (100 data sub-carriers and 18 pilot sub-carriers) and 1 9 overhead of CP are considered. With these values, symbol rate after 64-QAM modulation is 6.667 Gsymbol/s and symbol duration is 0.15 ns.…”

“…Time division multiplexing PON (TDM-PON) technologies have security risk on physical layer and interference between different optical network units (ONUs), i.e., beat noise [1]. Wavelength division multiplexing PON (WDM-PON) avoids the security risk by allowing the service provider to put each customer on a separate wavelength.…”

“…A consolidated CO serves several clusters of access networks (either AON or PON networks) centralizing the management of the system and employing a single physical platform. Furthermore, concerns on security [16] and high mobility [17] seem to indicate active solutions such AON may be in favor of system designers, provided that cost and energy consumption are maintained within reasonable limits. AON networks, in combination with RoF technologies, are hence an interesting way of enabling a higher degree of reconfigurability in scenarios in which the end user is mobile per se, and requires low-latency, high-throughput and physical layer security features.…”

“…Todavia, com relação ao upstream, o GPON considera que não há necessidade de encriptação, uma vez que, a alta direcionalidade dos componentes na rede de distribuição óptica (ODN) impede que uma ONU consiga receber os dados de outra ONU [25]. Porém, diferentememte do que foi Segundo operadores de redes americanas, a perda de retorno devido a conectores mal instalados é bastante elevada [34], sendo muito frequente encontrar conectores mal instalados em redes PONs em franco funcionamento [30].…”
