Mobile multimedia communication requires considerable resources such as bandwidth and efficiency to support Quality-of-Service (QoS) and user Quality-of-Experience (QoE). To increase the available bandwidth, 5G network designers have incorporated Cognitive Radio (CR), which can adjust communication parameters according to the needs of an application. The transmission errors occur in wireless networks, which, without remedial action, will result in degraded video quality. Secure transmission is also a challenge for such channels. Therefore, this paper’s innovative scheme “VQProtect” focuses on the visual quality protection of compressed videos by detecting and correcting channel errors while at the same time maintaining video end-to-end confidentiality so that the content remains unwatchable. For the purpose, a two-round secure process is implemented on selected syntax elements of the compressed H.264/AVC bitstreams. To uphold the visual quality of data affected by channel errors, a computationally efficient Forward Error Correction (FEC) method using Random Linear Block coding (with complexity of O(k(n−1)) is implemented to correct the erroneous data bits, effectively eliminating the need for retransmission. Errors affecting an average of 7–10% of the video data bits were simulated with the Gilbert–Elliot model when experimental results demonstrated that 90% of the resulting channel errors were observed to be recoverable by correctly inferring the values of erroneous bits. The proposed solution’s effectiveness over selectively encrypted and error-prone video has been validated through a range of Video Quality Assessment (VQA) metrics.

In this work, a method for detecting and correcting errors in Modbus-RTU communications is designed, implemented, and assessed in a smart metering application. This is a low-cost solution for improving communication quality in conventional Modbus-RTU architectures with copper fieldbus. It consists of introducing error detection and correction devices in the network segments most susceptible to errors caused by electromagnetic interference. Experimental validations were conducted and demonstrated the effectiveness of this method for isolating noisy segments in the communication bus, maintaining full compatibility with commercial devices and improving the performance of the entire network.

“…Secure communications is an important requirement of the digital infrastructure and it is necessary to provide reliable communication despite presence of malicious users jeopardizing the normal flow of communications [8]. Modbus-RTU [9] was released in 1979 and is a communications protocol in widespread use in industrial applications [10]. Many security loopholes found in SCADA networks are in the communications protocols [7].…”

Industrial control systems were designed as closed systems without any consideration or need for Internet connectivity. This design choice resulted in most SCADA protocol implementations being plain text with little security against attackers. Information on SCADA systems and protocols is readily available in public domain, making them a target for malicious attacks. Network coding is a lightweight technique based on simple XOR operations for error correction that can also help secure the message. This paper proposes use of network coding for protection of message interchanges with the field devices in an industrial network. The results show that the proposed method effectively protects the communications against a malicious adversary.
