Security and efficient data transmission without any hurdles caused by external Attackers is an issue in sensor networks. This paper deals with the provision of an assured efficient data transmission in the sensor networks. To ensure this requirement hash based Message Authentication Code (HMAC) and Message Digest (MD) is envisaged by employing identity based digital signature scheme (IBS). Identity based scheme is an encryption scheme that generates an operation of developing secret code with secret key that protects the data during transmission without any cryptanalysis. To achieve the above requisite the modalities used in HMAC and MD5 which simulates the functional efficiency & security of data transmission in sensor networks.

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.

引用

CRYPTOLOGIA 2013年第1期37卷 69-73页

作者： Dang, Quynh NIST Comp Secur Div 773 Informat Technol Lab Gaithersburg MD 20899 USA

This article describes the changes between Federal Information Processing Standards FIPS 180-3 and FIPS 180-4. FIPS 180-4 specifies two new secure cryptographic hash algorithms: secure hashing algorithms SHA-512/224 and SHA-512/256;it also includes a method for determining initial value(s) for any future SHA-512-based hash algorithm(s). FIPS 180-4 also removes a requirement for the execution of the message length encoding operation.

This paper presents a compact and unified hardware architecture implementing SHA-1 and SHA-256 algorithms that is suitable for the mobile trusted module (MTM), which should satisfy small area and low-power condition. The built-in hardware hash engine in a MTM is one of the most important circuit blocks and dominates the performance of the whole platform because it is used as a key primitive to support most MTM commands concerning to the platform integrity and the command authentication. Unlike the general trusted platform module (TPM) for PCs, the MTM, that is to be employed in mobile devices, has very stringent limitations with respect to available power, circuit area, and so on. Therefore, MTM needs the spatially optimized architecture and design method for the construction of a compact SHA hardware. The proposed hardware for unified SHA-1 and SHA-256 component can compute a sequence of 512-bit data blocks and has been implemented into 12,400 gates of 0.25 mu m CMOS process. Furthermore, in the processing speed and power consumption, it shows the better performance in comparison with commercial TPM chips and software-only implementation. The highest operation frequency and throughput of the proposed architecture are 137 MHz and 197.6 Mbps, respectively, which satisfy the processing requirement for the mobile application.

In most of the organizations, the use of Wireless Local Area Network (WLAN) is increasing promisingly. WLAN security is mainly affected by two internal attacks: Rogue Access Point (RAP) and Rogue Dynamic Host Configuration Protocol (DHCP) Server. Rogue Access Point is installed either by employees or by hackers. Employees install rogue access point for flexibility and scalability. Hackers install rogue access point to breach the security either internally or externally. DHCP server normally does not use authentication when servicing clients that needs dynamic IP address. To secure the organizations from network attacks it is necessary to detect the installation of rogue access point and rogue DHCP server. There are several methods to detect these attacks but still need arise for suggesting a method that provides solution for Address Resolution Protocol (ARP) spoofing. Since spoofing can easily be performed so it will be a major threat in wireless security. This paper presents a method to prevent this attack. The proposed approach uses hash algorithm to assure authenticity and integrity. The proposed solution is feasible and easy to implement.

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.

Analysis and improvement of a hash-based image encryption algorithm

COMMUNICATIONS IN NONLINEAR SCIENCE AND NUMERICAL SIMULATION 2011年第8期16卷 3269-3278页

The security of digital image attracts much attention recently. A hash-based digital image encryption algorithm has been proposed in Ref. [1]. But both the theoretical analysis and computer simulation show the characteristic of diffusion is too weak to resist Chosen Plaintext Attack and Known Plaintext Attack. Besides, one bit difference of the plain pixel will lead to only one corresponding bit change of the cipher pixel. In our improved algorithm, coupled with self-adaptive algorithm, only one pixel difference of the plain-image will cause changes of almost all the pixels in the cipher-image (NPCR > 98.77%), and the unified average changing intensity is high (UACI > 30.96%). Both theoretical analysis and computer simulation indicate that the improved algorithm can overcome these flaws and maintain all the merits of the original one.

This paper presents a DFA on Grostl-256, a hash algorithm that imitates the main structures of AES. Although our attack is inspired by the classical fault attacks on AES these could not be adapted directly. The attack is able to completely recover the whole input message using a one-bit and a random-byte fault model. It needs 16 errors to invert the output transformation Omega(n) and on average 280 errors for each compression step. When Grostl is used in a keyed hash function like HMAC, this attack is able to retrieve the secret key from about 300 faulty outputs in less than three minutes.

In this paper we present two new architectures of the RIPEMD-160 hash algorithm for high throughput implementations. The first architecture achieves the iteration bound of RIPEMD-160, i.e. it achieves a theoretical upper bound on throughput at the micro-architecture level. The second architecture is designed by performing a gate level optimization and achieves a better performance than the first one at the cost of a larger gate area. Throughputs of 3.122 Gbps and 624 Mbps are achieved, with and without pipelining, respectively.
