“…An endpoint might be a message sink or base station (BS), which passes data to the next layer of the architecture, as occurs in traditional sensor networks when a sink communicates over a satellite link. To ensure confidential communication of information in an IoT, many schemes have been proposed, schemes which employ existing state-of-art encryption algorithms [32][33][34][35][36][37][38]. A summary of the proposed encryption schemes for IoT with standard cipher algorithms is presented in Table 1.…”

Within an Internet of Multimedia Things, the risk of disclosing streamed video content, such as arising from video surveillance, is of heightened concern. This leads to the encryption of that content. To reduce the overhead and lack of flexibility arising from full encryption of the content, a good number of selective-encryption algorithms have been proposed in the last decade. Some of them have limitations, in terms of significant delay due to computational cost, or excess memory utilization, or, despite being energy efficient, do not provide a satisfactory level of confidentiality, due to their simplicity. To address such issues, this paper presents a lightweight selective encryption scheme, in which encoder syntax elements are encrypted with the innovative EXPer (EXtended Permutation with exclusive OR).  The selected syntax elements are taken from the final stage of video encoding that is during entropy coding. As a diagnostic tool, the Encryption Space Ratio measures encoding complexity of the video relative to the level of encryption so as to judge the success of the encryption process, according to entropy coder. A detailed comparative analysis of EXPer with state-of-the-art algorithms confirms that the EXPer provides significant confidentiality with a small computational cost and negligible encryption bitrate overhead. Thus, the results demonstrate that the proposed security scheme is a suitable choice for constrained devices in an Internet of Multimedia Things environment.

“…However, the proposed system uses complex algorithms at each layer which makes it unsuitable for limited power components like sensors and RFID which are regarded as skeleton for IoT. A hybrid encryption technique is proposed in [61] for safeguarding the data in IoT devices. The cryptographic methods used in this technique include Advanced Encryption System (AES) and Elliptic Curve Cryptography (ECC), but these methods are highly complex and drain off the limited battery of nodes rapidly and thus unsuitable for IoT.…”

Internet of things (IoT) is gaining popularity now-a-days as it is revolutionizing the world of internet and physical systems in a more advanced and technical way. IoT consists of physical things in which sensing, processing and communication capabilities are added. These devices have restricted resources and processing competences. The networks formed from these miniature devices have a lot of scope and applications that include healthcare, industrial automation, military surveillance, forest fire detection, flood alarming system, smart homes, smart cities etc. Most of these applications demand secure transmission of sensed information from source IoT node to gateway node or broker. Thus, it is imperative to pay attention to the security of these networks as they are highly susceptible to risks because of wireless medium used for communication and the constrained nature of these devices. In this paper, we have presented a variety of attacks that can harm the fidelity of transmitted information in IoT, thereby generating unauthorized effects. Furthermore, various counter measures against these possible attacks that have been proposed in the literature with their merits and demerits are presented, together with possible research opportunities for future work.

A pervasive network architecture that interconnect heterogeneous objects, devices, technologies and services called Internet of Things has prompted a drastic change in demand of smart devices which in turn has increased the rate of data exchange. These smart devices are built with numerous sensors which collect information from other interacting devices, process it and send it to remote locations for storage or further processing. Although this mechanism of data processing and sharing has contributed immensely to the information world, it has recently posed high security risk on privacy and data confidentiality. This paper therefore analyses different security threats to data at different architectural layers of Internet of Things, possible countermeasures and other in-depth security measures for Internet of Things. The paper identifies device authentication on IoT network to be of paramount importance in securing IoT systems. This paper also suggests some essential technologies of security such as encryption for securing IoT devices and the data shared over IoT network.
