“…In Table 6, the secure routing protocols have been compared to the next-generation features in WMSNs. This table shows that most of the protocols (Wang et al [4], [17], and Lin et al [11]) that have been proposed thus far are only for WMSNs. Only a few of the recently proposed protocols (Zhou and Chao [12], MDSAH [13], and Porambage et al [14]) have been developed to maintain and secure the data traffic over a heterogeneous network.…”

Multimedia applications are gradually becoming an essential—and flourishing—part of our daily lives. The area of wireless sensor networks is not an exception to this trend, as multimedia data have attracted the attention of researchers. Their importance is due to the shift of focus from traditional scalar sensors to sensors equipped with multimedia devices, as well as to the next-generation wireless multimedia sensor networks (WMSNs). The highly sensitive nature of multimedia traffic makes data routing with security even more important in WMSNs. This paper discusses the challenges of secure routing in WMSNs, where most of the proposed works in the literature deal with routing and security as individual issues. A critical and comprehensive review of state-of-the-art routing and security approaches for WMSNs is presented, followed by the discussion of their limitations and features. It is hoped that this extensive review and discussion ultimately identifies the future research directions and the open challenges of secure routing approaches in WMSNs.

“…If a Fog platform or network contains any bugs due to lack of diligence, the crucial video stream might be viewed, altered and even destroyed. It is important that Fog node ensures a secure connection between all communicating devices and protect multi-media content by obfuscation techniques, finegrained access control, generating a new link for video stream, selective encryption and limiting the number of connections [66].…”

Fog computing is a new paradigm that extends the Cloud platform model by providing computing resources on the edges of a network. It can be described as a cloud-like platform having similar data, computation, storage and application services, but is fundamentally different in that it is decentralized. In addition, Fog systems are capable of processing large amounts of data locally, operate on-premise, are fully portable, and can be installed on heterogeneous hardware. These features make the Fog platform highly suitable for time and location-sensitive applications. For example, Internet of Things (IoT) devices are required to quickly process a large amount of data. This wide range of functionality driven applications intensifies many security issues regarding data, virtualization, segregation, network, malware and monitoring. This paper surveys existing literature on Fog computing applications to identify common security gaps. Similar technologies like Edge computing, Cloudlets and Micro-data centres have also been included to provide a holistic review process. The majority of Fog applications are motivated by the desire for functionality and end-user requirements, while the security aspects are often ignored or considered as an afterthought. This paper also determines the impact of those security issues and possible solutions, providing future security-relevant directions to those responsible for designing, developing, and maintaining Fog systems.

“…Additionally, these variables add complexity to cryptography, since the costs for video compression and transmission are already high. Thus, an encryption algorithm for video streaming should possess at least two characteristics [56]. First, the encryption time should be low to avoid transmission delays, and second, the compression rate of the video should not decrease.…”

“…For predictive video codecs, compression is achieved exploiting information in the video frames: the redundancy within one frame is typically reduced exploiting spatial correlation, while inter-frame coding reduces the redundancy in subsequent frames exploiting both spatial and temporal correlation [56]. As a result, frames with different relevancies for reconstruction are created, and the most relevant ones may be encrypted for security reasons.…”
