Abstract:
Nowadays, the Passive Optical Networks (PONs) technology is widely deployed in broadband access networks.
This paper deals with the security issues of Gigabit PON (GPON) standardized by the International
Telecommunications Union (ITU), namely, standard ITU-T G.984 that is widely implemented in Europe these
days. We describe and analyze the security of this standard and show its security risks. In spite of that transmitted
data are encrypted to provide their confidentiality on a multipoint fibre connection, session secret keys
during their establishment can be observed by adversaries. To address this security flaw, we propose a key establishment
protocol that securely sets the session secret keys between two communication parties in GPON.
Furthermore, we provide the security analysis of the proposed protocol.
