Security considerations for IPv6 Packets over Short-Range Optical
Wireless Communications
draft-choi-6lo-owc-security-00
Abstract
IEEE 802.15.7, "Short-Range Optical Wireless Communications" defines
wireless communication using visible light. It defines how data is
transmitted, modulated, and organized in order to enable reliable and
efficient communication in various environments. The standard is
designed to work alongside other wireless communication systems and
supports both line-of-sight (LOS) and non-line-of-sight (NLOS)
communications. This document describes security considerations for
short-range optical wireless communications (OWC) using IPv6 over
Low-Power Wireless Personal Area Network (6LoWPAN) techniques.

1. Introduction
The rapid growth of the Internet of Things (IoT) has led to a
significant increase in the number of wireless communication
technologies utilized for real-time data collection and monitoring in
various industrial domains, such as manufacturing, agriculture,
healthcare, transportation, and so on. This trend highlights the
importance of wireless communication in facilitating real-time data
exchange and analysis, ultimately contributing to enhanced
operational efficiency and decision-making processes across different
industrial sectors.
Optical Wireless Communications (OWC) stands as one of the potential
candidates for IoT wireless communication technologies, extensively
applied across various industrial domains. The IEEE802.15.7 standard
outlines the procedures for establishing bidirectional communications
between two OWC devices. Furthermore, IEEE 802.15.7 delineates a
comprehensive OWC standard, encompassing features like Visible Light
Communication (VLC), Short-Range Communication, Line-of-Sight (LOS)
and Non-Line-of-Sight (NLOS) Support, High and Low Data Rates, Energy
Efficiency, and Secure Communication.
This document describes security considerations for IPv6 over Optical
Wireless Communications.

2. Security Considerations
Optical Wireless Communication (OWC) systems introduce unique
security concerns due to their reliance on visible or infrared light.
Below are key security considerations.
2.1. Eavesdropping and Data Interception
Since OWC transmissions occur via light, they are more prone to
interception if there is an unobstructed line of sight. Mitigation
includes using directional communication, encryption of data, and
limiting transmission power to reduce signal leakage.
2.2. Data Integrity
OWC may be affected by environmental factors like obstacles,
reflections, or interference, which could corrupt data. Error
detection and correction techniques such as checksums or
cryptographic hashing are necessary to ensure data integrity.
2.3. Denial of Service (DoS) Attacks
OWC systems are susceptible to physical blockages or jamming attacks,
where an attacker disrupts communication by introducing noise or
obstructions. To mitigate this, the system could implement fallback
mechanisms or use alternative communication pathways when a block is
detected.
2.4. Authentication and Access Control
Devices connecting to the OWC network must be authenticated to
prevent unauthorized access. Using mutual authentication protocols
like DTLS (Datagram Transport Layer Security) can secure device
communication.
2.5. Key Management
Secure key management is essential to ensure encryption and
integrity. Methods like public-key infrastructure (PKI) or pre-
shared keys should be employed to establish trust between OWC nodes.
2.6. Energy Efficiency and Security Trade-off
Given the low power nature of OWC systems, security protocols should
be lightweight to minimize additional energy consumption while still
providing sufficient security. Optimized encryption algorithms for
resource-constrained environments, such as lightweight ciphers, can
be considered.
