A Lightweight Protocol for Secure Video Streaming

Area of Science:

• Computer Science
• Cybersecurity
• Network Engineering

Background:

• Traditional cloud and host computing models face challenges with Internet of Things (IoT) security.
• Fog computing emerges as a solution for IoT, but requires new security approaches for resource-constrained end devices.
• Existing security protocols like Transport Layer Security (TLS) are often unsuitable for fog computing environments due to limited energy and computational power.

Purpose of the Study:

• To introduce a novel, lightweight secure streaming protocol specifically designed for the Fog Node-End Device layer in fog computing architectures.
• To address the security gaps in fog computing by providing essential security services like data source authentication, integrity, and confidentiality.
• To develop a protocol that is efficient in terms of energy and computational resource usage.

Main Methods:

• The proposed protocol utilizes simple and energy-efficient cryptographic methods, including Hash Message Authentication Codes (HMAC) and symmetric ciphers.
• It employs modified User Datagram Protocol (UDP) packets to embed authentication data directly within streaming data.
• The protocol is connectionless, supports broadcast and multicast, and can incorporate data redundancy for enhanced reliability in lossy networks.

Main Results:

• Experimental results demonstrate that the protocol efficiently conserves energy and computational resources.
• The protocol achieves security properties comparable to the established Datagram TLS (DTLS) standard.
• The lightweight design makes it suitable for resource-limited fog computing end devices.

Conclusions:

• The developed lightweight secure streaming protocol effectively enhances security in fog computing environments.
• It provides a viable and efficient alternative to traditional security protocols for IoT devices with limited resources.
• The protocol's performance validates its suitability for securing the Fog Node-End Device layer, balancing security with resource efficiency.
