The SHA-3 cryptographic hash algorithm is standardized in FIPS 202. We present a pipelined hardware architecture supporting all the four SHA-3 modes of operation and a high-performance implementation for FPGA devices that can support both multi-block and multi-message processing. Experimental results on different FPGA devices validate that the proposed design achieves significant throughput improvements compared to the available literature.

hash functions are widely used in encryption schemes and security layers of communication protocols for data integrity, digital signature and message authentication codes[18]. hash function is a well-defined procedure that converts a large data into a small one, The returned value from hash function is called hash code, It is well known that hash algorithm works in one way and cannot be reversed, In this paper, The new one way hash algorithm will be designed by using two steps. Firstly, we will convert the input data into matrix system by using all necessary conversions to generate the initial hash value. Secondly, use the output of the first step to make a digest for these data and finally generate the secure hash value.

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.

作者： Jianqiang Li South China Agricultural University

Block chain technology and satellite integration to achieve wide-area security transactions has become a hot topic in the field of information security. It will face two major problems: the real-time transmission of large-span digital currency and the credibility of digital currency transmission under complex interference. In order to solve the above problems, this paper proposes a multi-constrained optimization-based hashing algorithm for long-span digital currency transactions. By analyzing satellite communication means and one-way hashing operation, the relationship between time delays under long-span digital currency transmission is obtained. By optimizing the hashing operation of constraints, the algorithm is improved to a larger extent. The adaptive ability of bit error rate（BER） and the construction of digital token based on multi-constraint enhanced hash algorithm provide a reliable authentication benchmark for digital currency transactions, design a large-span digital currency transaction process, and effectively suppress the information leakage caused by interference in the transmission process. The simulation results show that the performance of the proposed algorithm is greatly improved in security and complexity.

In this paper, a new incremental knowledge acquisition method is proposed based on rough set theory, decision tree and granular computing. In order to effectively process dynamic data, describing the data by rough set theory, computing equivalence classes and calculating positive region with hash algorithm are analyzed respectively at first. Then, attribute reduction, value reduction and the extraction of rule set by hash algorithm are completed efficiently. Finally, for each new additional data, the incremental knowledge acquisition method is proposed and used to update the original rules. Both algorithm analysis and experiments show that for processing the dynamic information systems, compared with the traditional algorithms and the incremental knowledge acquisition algorithms based on granular computing, the time complexity of the proposed algorithm is lower due to the efficiency of hash algorithm and also this algorithm is more effective when it is used to deal with the huge data sets.

In order to improve the ability of searching and identifying information in natural resources data, this paper puts forward a method of searching information in natural resources data based on hash algorithm. Through the data center technology, the problems of information source positioning, data directory organization, data semantic definition and expression, and data entity relationship construction in natural resource data center are solved. Combined with the distribution of resource data stream, the information structure reorganization and data encryption in natural resource data center are realized by using hash algorithm, and the parameters of information quality control model in natural resource data center are established. Through natural resource data governance and semantic reconstruction, the characteristics detection and redundancy arrangement of information data in natural resource data center are realized by standardizing data collection rules, and they are stored in the intermediate database. Through data governance rules, the information in the natural resources data is structured and managed, and stored in the publishing library. Through all kinds of data processing tools, all kinds of data are processed, cleaned and reconstructed, and through hash algorithm and data aggregation processing, information detection in natural resources data is realized. The simulation results show that the precision rate of natural resource data retrieval by this method is high.

Anew compact belief rule model for fault diagnosis

CONTROL ENGINEERING PRACTICE 2025年 159卷

Amidst growing scrutiny of "black box" models in fault diagnosis applications that demand high interpretability, rule-based models are regaining prominence due to their inherent interpretability. Belief rule-based (BRB) models with belief distributions stand out in fault diagnosis. Nevertheless, the incorporation of multiple fault features introduces a substantial challenge for the BRB modeling, due to the phenomenon of combinatorial explosion, which leads to an exponential escalation in the number of rules required. To tackle the root cause of the exponential growth of rules in the BRB model, anew compact belief rule model (CBRM) for fault diagnosis is proposed. A flexible rule antecedent that leverages the similarity of reference values, eschewing the Cartesian product structure, is proposed to effectively diminish the complexity and size of the fault diagnosis model. Consequently, a rule activation method leveraging the hash algorithm has been proposed, wherein the spatial relationship between a sample and a rule is translated into binary code. The rule closest to the sample in each space is activated, and its corresponding activation weight is calculated combining the matching degree, fault features weights and rules weights. Subsequently, the reasoning and optimization of the CBRM are conducted to grab the diagnostic results and update parameters. Eventually, the fault diagnosis for relays is utilized to validate the proposed method.

Healthcare is no exception to the requirement of cutting-edge solutions for healthcare data security and privacy: novel strategies need be formulated on a regular basis given contemporary threat in order to reliable shield over sensitive information. We therefore introduce in this paper a novel technique to increase the data security and privacy of cloud-based healthcare systems. We employ state-of-the-art encryption mechanisms such as Spectrasafe algorithm, Facile hash algorithm and Dynamic k-anonymity (DKA algorithm) to protect healthcare data at rest and during transit. Conducting a series of performance comparisons, using this high-quality data meticulously prepared from Kaggle to compare it with existing methods SMPC (Secure Multi-Party Computation), MSHC (Multi Server Homomorphic Encryption), AHC-ASS (Attribute-Hiding Cryptography with Attribute-Based Secret Sharing), MP-FHE(Multiparty Fully Homomorphic Encryption). Our encryption and decryption runtime are intensive computationally, with an average runtime of 99 ms and 108 ms, respectively. In terms of memory size our approach is 25 % smaller than existing state-of-the-art methods which indicates that it has a higher efficiency. Our method attains a detection accuracy of 95 %, which is also significant than results of previous methods. Moreover, the proposed method is shown to scale across a wide variety of healthcare datasets and updated requirements seen in modern healthcare systems. We intend to make a significant contribution towards secure and efficient healthcare data management in cloud environments, by extending the proposed privacy preservation mechanisms.
