A new multicast group join/leave mechanism for mobile nodes (MNs) is proposed. The mechanism is based on hash algorithm. This paper explains the construction of a dynamic delivery tree of the mobile node movement for a multicast-based mobile IPv6 network, such that the branches of the tree constitute the shortest paths from the packet source to each of the visited locations. The branches of the tree grow and shrink to reach the mobile node when necessary. The mobile node is assigned a multicast address and the correspondent nodes (CNs) send packets to the multicast group. As the mobile node moves to a new location, it joins the multicast group through the new location and prunes through the old location. The performance of the proposed mechanism was evaluated through a simulation model built. or this purpose. Simulation results show that the dynamics of joining and leaving the group directly affect handoff latency and smoothness, as a result it conserve Radio Frequency (RF) bandwidth.

At the present, paper-based libraries are a big challenge in Afghan educational organizations. This study proposes a high-tech library management system namely "e-Ketabtoon". It aims to improve the overall working of a library, digitalize and preserve Afghan valuable knowledge and cultural heritage for the next generation, and promote digital literacy among Afghan masses. The system architecture splits into two parts: server responsiveness capacity and client request capacity. We used agile development method which keeps users at the center of design process to develop valuable system. The initial lab tests indicate satisfying accuracy in term of usability.

hash algorithms have been widely used for cryptography. It has been impossible to decrypt the ciphertexts generated through hash algorithms, as an operation that damages the original text is performed. However, various methods of attack occurred over time after the algorithm was developed. The vulnerability of SHA1 (an old hash algorithm) has been revealed, and there has been a great deal of data available for dictionary attacks. Although the industry has been gradually refraining from using SHA1, it remains in use in some existing systems for various reasons. For example, when problems resulting from service interruption or mass update are critical, updating the encryption algorithm can be a burden. In this study, we aim to increase the complexity of ciphertexts by postprocessing hash ciphertext. For that, image salting techniques are used using two-dimensional array masking. This will allow the use of hash ciphertexts with increased complexity in some devices that are forced to use old hash algorithms for various reasons.

The specialties and limitation of RFID system and device will incur lots of security problems especially when the system contains a lot of tags and many readers, the traditional methods become helpless. Here we present and analyze an improved hash key technique based on multiple readers. RFID (Radio Frequency Identification) is to become a reality, because modem supply chains require higher performance, greater information flow and flexibility. RFID products have been widely used in the retail, pharmaceuticals, transportation, defense, and with packaging consumer goods industry. RFID technology can improve the forecast level and container security, Reduce the occurrence of the problem of cargo shrinkage, recall and stock at the same time, thus saving billions of dollars in the cost of the supply chain. Wal-Mart, Albertson's and Best Buy and other retailers have asked their top suppliers to all enabled RFID in late 2005. These requirements extended to. thousands of suppliers, stores and distribution centers, and they need to assemble a multifunction distributed reader, which raises several technical challenges. Now, the majority of enterprises using RFID technology are concentrated in a small-scale pilot and one-stop concept validation. However, in order to realize the benefits of RFID, the technology must be adopted in the enterprise-wide.

This paper introduces a tool suitable for rapid packet processing - DPDK and two frameworks for packet processing based on DPDK. Then we surveyed and analyzed a number of traditional load balancing algorithms. After that we expounded the different ways to classify traffic according to different rules under DPDK. With respect to RSS technology, we compared several hash algorithms used in RSS technology. Finally, we introduced a dynamic load balancing method.

To overcome the shortcomings of the current popular conflict-free generation algorithm for pseudo-random sequences, a new conflict-free and efficient random permutation generation algorithm is presented. At the same time, it also introduces two other classical pseudo-random sequences generation algorithms, hash algorithm and GUID algorithm. Compare the performance of the three algorithms by calculating time complexity and recording time consumption. The results show that the random permutation generation algorithm has high time efficiency and is more suitable for generating large amounts of conflict-free pseudo-random sequence.

This letter presents a new type of chaotic encryption system based on combined chaotic mapping pseudo-random number generator, hash table, and elliptic curve. In this program, the elliptic curve algorithm is used for the key distribution. After the linear transformation, the original chaotic sequence generated by drive system will be combined to chaotic mapping, converted to an encryption key sequence and constructed as hash table for message authentication. The communication experiment used in the letter proves that the combination of combined chaotic encryption and conventional encryption is safe, feasible, and easy to implement by software.

Rapid development of computer is followed by development of digital storage device. One common problem of digital storage device is data loss. The problem of data loss could be solved by using file carving techniques, for example. File carving techniques could be performed using carving tools, such as PhotoRec and Foremost. This research was conducted to know and to compare performance of carving process from PhotoRec and Foremost based on three parameters, which are the number of return files, file validation, and the rate of process. The research used simulation methods. The process of file validation uses hash algorithm SHA1 to make sure the similarity between original and return files. The result of this research shown with table that PhotoRec has a higher performance than Foremost. PhotoRec have return files less than Foremost, but PhotoRec has a higher percentage of valid files than Foremost. Additionally, the rate of carving file process done by PhotoRec is higher than Foremost. Finally, the research reaches the conclusion that PhotoRec is better than Foremost.

Surveilling the water territory of a country by installing an Underwater Surveillance Network (USN) is one of the prominent applications developed for underwater communication. The primary responsibility of a USN is to detect trespassers within the premises and to notify the activities to the responsible authority for further actions. Alike any surveillance network, a USN also possesses several security threats and may undergo several passive and/or active attacks. In this paper, we propose a noble secure communication suite which is resistible against most kind of known attacks. Our propose protocol aimed at gaining confidentiality, integrity and authenticity of the messages being exchanged within the cluster while taking into the consideration of the peculiarities of the underwater communication. Moreover, since our proposed scheme is designed for a cluster-based USN where routing layer activities are not eminent, it is embedded within a media access control (MAC) protocol.

The electric vehicles nowadays arc managed by networked controllers. Because of the advantages of fast, reliable, simple wiring, and light weight, CAN bus has become one of the most widely used field buses in the world. Most of the networks were designed with little concern about security which has recently motivated researchers to demonstrate various kinds of attacks against the system. This paper proposes an optimization method for encrypting CAN Messages. In addition, a single frame CAN message can only transmit 64-bit valid data, it is often necessary to complete the communication task by sending a multi-frame message with the same ID. The AES algorithm has become the first choice for encrypting multi-frame CAN messages with its extremely high reliability and fast encryption and decryption speed. In this paper, a method of encrypting multi-frame CAN messages based on the AES algorithm is proposed, and on the basis of which a hash value is optimized to ensure the security of data transmitted on the CAN bus.
