Abstract

Wireless sensor networks (WSNs) have been the subject of intensive research in the past few years and the backbone of most maximum present information technology. WSNs have been employed in various applications such as track monitoring battlegrounds in military fields and patients’ medical requirements in the civilian field. The wireless sensor networks are always randomly distributed in an open area (hostile), pervasive environment, and open media channel. Thus, WSNs are vulnerable to several species of attacks. Moreover, messages may be easily intercepted or altered because the transmission is not secure, hence effective key management scheme is strongly needed to reduce the risks. Cryptography methods are a crucial aspect of WSNs to reach security goals. In this paper, we propose an efficient and secure message transmission scheme that combines the Knapsack algorithm with the Diffie-Hellmann process to encrypt messages. The results and analysis show that the proposed scheme is efficient and it achieves most of the security goals providing high privacy and security. It is also resilient against some of the well-known attacks.

Abstract

The wireless technology is in consistent and rapid development in this century such that it produces fast data rate and strong connectivity. Mobile ad hoc network (MANET) is an independent network wherein nodes function as both host and router. Routing protocols in MANET are prone to different attacks. Malicious nodes usually interfere the process of establishing routes and make it hard to build a valid route. In the literature, different mechanisms proposed to prohibit black hole attacks in which an adversary node blindly drops data packets. In this paper, a study is fulfilled of the advantages and disadvantages of some of the protocols presented in the literature and a novel method proposed that detects black hole attacks. A thorough, precise, and theoretical analysis is presented to show how the proposed method can prevent malicious nodes from impersonating benign nodes. A theoretical compareison conducted between the proposed method and some of the other methods presented in the literature. The comparison shows that the attacks exist on these protocols are detected and prevented by the proposed protocol.

Abstract

With the increasing interest of cloud computing users in storing and processing their data, the need for secure and permanent data deletion has grown. This research paper proposes a practical, evaluable, and testable mechanism for verifying data integrity and ensuring its deletion. The proposed system integrates sequential XOR technology with AES-based block-level encryption, thereby achieving strong interconnection between encrypted blocks. This prevents block separation, decryption, or tampering during transmission and storage. The encryption key is divided into independent parts, the purpose of which is to prevent any single party from possessing the complete encryption key. This ensures that the file cannot be recovered if any part of the key is deleted. The encrypted blocks are then arranged with one of the key parts in a Merkel tree structure to guarantee data integrity and verifiability during storage and retrieval. Through experimentation and providing similar levels of confidentiality and data recovery, the experimental results showed that this mechanism achieves competitive computing efficiency with reasonable storage and communication costs compared to basic methods. This solution was implemented on a real cloud platform within the Microsoft Azure environment, proving its feasibility, security and reliability without the need for major modifications to the existing cloud infrastructure.
