“…While in-compression class depends on the compressor and requires a modification in the standard, the post-compression class is more efficient since it preserves the compression efficiency independently of the compressor. Moreover, a recent post-selective image crypto-compression scheme was presented in [366,367]. It consists of selecting randomly (uniform distribution) only 5% of the compressed data to reach a high visual degradation.…”

The recent digital revolution led robots to become integrated more than ever into different domains such as agricultural, medical, industrial, military, police (law enforcement), and logistics. Robots are devoted to serve, facilitate, and enhance the human life. However, many incidents have been occurring, leading to serious injuries and devastating impacts such as the unnecessary loss of human lives. Unintended accidents will always take place, but the ones caused by malicious attacks represent a very challenging issue. This includes maliciously hijacking and controlling robots and causing serious economic and financial losses. This paper reviews the main security vulnerabilities, threats, risks, and their impacts, and the main security attacks within the robotics domain. In this context, different approaches and recommendations are presented in order to enhance and improve the security level of robotic systems such as multi-factor device/user authentication schemes, in addition to multi-factor cryptographic algorithms. We also review the recently presented security solutions for robotic systems.

“…Selective encryption reduces the computational complexity to the minimum possible level while preserving a sufficient security level. The selective approach is debatable since the most existing schemes are designed based on image compression algorithms, and thus they are codec-specific, while the rest are applied at the pixel level (14), (15)- (23). Recent research works presented a new kind of compression algorithms that are specific for encrypting image and video, and can ensure good performance such as (24)- (27).…”

Protecting the contents of medical records is of paramount importance when it comes to preserving patients' privacy. Most existing cryptographic-based solutions rely on traditional encryption algorithms having a multi-round structure, which introduces processing latency and requires increased resources. Medical images possess special characteristics compared to other types of images. The main goal of this paper is to leverage these characteristics to design and implement an efficient and secure encryption algorithm for such images. The proposed solution defines three variants of encryption algorithms: (a) full, (b) middlefull, and (c) selective. The full approach encrypts all sub-matrices of an image, while the middle-full variant is a middle solution between the selective and full algorithms and its goal is to just hide the type of the medical image. Selective encryption identifies a set of sub-matrices of an image according to a statistical average test, known as region of interest (ROI). In the three approaches, a high security level is ensured since each image is encrypted independently of the previous and next images. Also, all primitives of the proposed cipher, such as permutation and substitution, depend on a dynamic key. Furthermore, the encryption scheme is efficient since the proposed round function is lightweight and applied for only one round. This reduces the latency and the required resources as compared to traditional cryptographic schemes. The proposed approach is flexible as it can be applied in either selective, middle-full, or full mode. Also, the size of a sub-matrix is variable and can be changed according to the available memory size. Several security and performance tests are conducted to evaluate the effectiveness of the proposed solution. The results validate the robustness of the proposed scheme against almost all considered types of attacks and show an improvement in terms of latency and resources compared to current image-encryption schemes. Also, the results confirm the robustness of the proposed algorithm in protecting the contents of medical images.

“…These requirements are somehow orthogonal and some previous research works have addressed only parts of these requirements and not all (see next section). For instance, the approach presented in [3] has addressed the three first requirements mentioned above. In fact, based on Voronoi tessellation, this approach has demonstrated its efficiency in terms of significant data reduction as well as in terms of data confidentiality preservation.…”

“…In this paper, we investigate, in addition to previously mentioned requirements, the issue of resilience to frequent transmission errors and active attacks. To this end an based on Voronoi tesselation approach [3], we propose a novel mechanism (new transmission protocol coupled to an image filtering approach) to cope with these two major issues. In fact, instead of relying on retransmission protocols, the receiver could recover the missed or corrupted data through appropriate content processing techniques (i.e., image filtering).…”
