Network-wide conveying is vital in remote associations, and the great part of these broadcasts are built on single-channel single-radio (SC-SR) network frameworks. The problem of the current work is divided into two parts. The first part shows that increasing broadcast and redundancy lead to an increase in time consumption. The second problem is solving complexity problems when tasks are scheduled in a heterogeneous manner in a computing system, where the processors in the network may not be identical and take different time periods to carry out the same task. The goals of this work are to reduce the total cost of network-wide broadcasting to minimize the search space and to solve the complexity problem when tasks are scheduled in a heterogeneous way in the computing system. The MOCAB algorithm is used to select the best transmission path over the network in the first stage. Then, the tasks will be scheduled using the heterogeneous earliest finish time (HEFT) algorithm to extract the values of actual finish time (AFT), earliest start time (EST), and earliest finish time (EFT). The performance of the MOCAB algorithm was evaluated with that of the HEFT algorithm in terms of the delivery ratio of packets delivered. The results showed that the MOCAB algorithm outperformed the HEFT.

“…Key spacing is defined as the number of distinct secret keys it can generate. The cipher is secure if the key spacing is at least 2100 [21]. The proposed algorithm uses an image that acts as a key to encode the message based on its dimensions, so the key size is 2 𝑟 * 𝑐 * 3 , The dimensions of the row (r) and column (c) will be variable according to the size of the image used for encryption, and this gives the algorithm the power to counteract a brute force attack.…”

Network security has recently become a major issue since the growth of electronic data exchange so cryptography is important in protecting secure online data resources from integrity, confidentiality, and safety perspective against potential attacks such as eavesdropping and brute force. In this paper, we proposed a method for encrypting the transmitted information based on an image, which worked as a key that is saved by the client and the server. The encryption process of the text will be to encode characters by changing the ASCII code of characters with the locations (row and column) of the ASCII code equivalent in the image data, the locations will be chosen randomly. The proposed algorithm provides a relatively greater degree of security in avoiding avalanches, eavesdropping attacks, and password space because the character encoding method will be dynamic depending on the size and type of image used. Several securities analyses were presented, and the proposed algorithm proved to be highly secure. Compared to some current text cypher schemes, the proposed algorithm is very safe against modern cryptanalysis.

“…Graphical passwords have been categorized into four main schemes: drawmetric (pure-recall-based), locimetric (cued-recall-based), cognometric (recognition-based), and hybrid [72]. In general, graphical password systems have various usability and security advantages such as being easy to remember and difficult to guess, higher security level, being human-friendly, and mitigating dictionary attacks; however, they are vulnerable to shoulder-surfing attacks and brute-force attacks (which reduce the common areas in the images) [73].…”

Knowledge-based passwords are still the most dominant authentication method for securing digital platforms and services, in spite of the emergence of alternative systems such as token-based and biometric systems. This method has remained the most popular one mostly because of its usability, compatibility, affordability of implementation, and user familiarity. However, the main challenge of knowledge-based password schemes lies in creating passwords that provide a balance between memorability and security. This research aimed to compare various knowledgebased schemes in order to establish a strategy that provided high memorability and resilience to most cyberattacks. The overview of this research identifies areas of knowledge-based passwords for further research and enhances the methodology that helps to offer insight into usable, secure, and sustainable authentication approaches. Future work has been recommended to explore the major features and drawbacks of recognition-based textual passwords because this method provides the usability and security benefits of graphical passwords with the familiarity of textual passwords.
