摘要：
The computing capability of micro encryption devices has been a concerned problem by the people. This paper improves the implementation of LILLIPUT which was proposed in 2016. In this paper, we adopt the method of compromising area and power consumption. And with the utilization of parallel hardware processing and reduced excess hardware, the execution speed of the algorithm is extended with the minimal power consumption. Tested by experiments, the third-order LILLIPUT algorithm of parallel processing is 40% higher than that of the non-parallel processing, with only a small amount of area and power consumption used to significantly improve the computing performance of the micro-equipment. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

摘要：
Digital image has the characteristics of high redundancy and convenient processing, which is the ideal carrier of information hiding application. Therefore, digital image steganography has become a hot research direction in the field of information security. In order to ensure the concealment, reliability and security of image steganographic information, an image adaptive steganographic algorithm combining chaotic encryption and minimum distortion function is designed. The algorithm generates random keys, encrypt the secret information using Logistic and ChebyShev mapping, and then embeds the key and the encrypted secret information into the carrier image using the HILL steganographic algorithm. The algorithm stores the embedded key and the decryption key separately, so the attacker cannot get the correct secret information even if he gets the embedded key, which improves the security of the key. Experiments show that the pixel change rate of the algorithm is 6.76%, the peak signal-to-noise ratio is 59.51 db, and it has a very good anti-steganographic analysis ability. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

FPGA implementation;Khudra;Lightweight block cipher;Optimization
摘要：
In this paper, we discuss the area and speed balance optimization of Khudra lightweight block cipher. There are three major ingredients. Firstly, because of the whole structure of the Khudra block cipher and its F-function is based on a Feistel structure, we make the main module that directly calls the F-function in the hardware optimization implementation. Secondly, through the clock control, the plaintext can be XORed with the key and the round constant under certain conditions. At the same time, the three rounds of the F-function are merged into one module, whose F-function module contains the F-function of the left and right branches of the algorithm. Thus, three rounds of operations can be completed with only one S-box, which can effectively reduce the number of registers and the number of iterations to increase the encryption and decryption rate. Finally, because of the particularity of key expansion in Khudra, we separately calculated the round key and stored its results in the register, which can effectively save the time of key expansion. © 2021, Springer Nature Singapore Pte Ltd.

摘要：
Recent studies have indicated that microRNAs (miRNAs) are closely related to sundry human sophisticated diseases. According to the surmise that functionally similar miRNAs are more likely associated with phenotypically similar diseases, researchers have proposed a variety of valid computational models through integrating known miRNA-disease associations, disease semantic similarity, miRNA functional similarity, and Gaussian interaction profile kernel similarity to discover the potential miRNA-disease relationships in biomedical researches. Taking account of the limitations of previous computational models, a new computational model based on biased heat conduction for MiRNA-Disease Association prediction (BHCMDA) was proposed in this paper, which can achieve the AUC of 0.8890 in LOOCV (Leave-One-Out Cross Validation) and the mean AUC of 0.9060, 0.8931 under the framework of twofold cross validation, fivefold cross validation, respectively. In addition, BHCMDA was further implemented to the case studies of three vital human cancers, and simulation results illustrated that there were 88% (Esophageal Neoplasms), 92% (Colonic Neoplasms) and 92% (Lymphoma) out of top 50 predicted miRNAs having been confirmed by experimental literatures, separately, which demonstrated the good performance of BHCMDA as well. Thence, BHCMDA would be a useful calculative resource for potential miRNA-disease association prediction. © Copyright © 2020 Zhu, Wang, Zhao, Pei, Kuang and Wang.

摘要：
Generating an RGB image from a sketch is a challenging and interest-ing topic. This paper proposes a method to transform a face sketch into a color image based on generation confrontation network and edge optimization. A neural network model based on Generative Adversarial Networks for transferring sketch to RGB image is designed. The face sketch and its RGB image is taken as the training data set. The human face sketch is transformed into an RGB image by the training method of generative adversarial networks confrontation. Aiming to generate a better result especially in edge, an improved loss function based on edge optimization is proposed. The experimental results show that the clarity of the output image, the maintenance of facial features, and the color processing of the image are enhanced best by the image translation model based on the generative adversarial network. Finally, the results are compared with other existing methods. Analyzing the experimental results shows that the color face image generated by our method is closer to the target image, and has achieved a better performance in term of Structural Similarity (SSIM). © 2020, Tech Science Press.

摘要：
人工化学反应优化算法（ACROA）是一种模拟化学反应过程的元启发式算法,它把化学反应中的对象、状态、过程和事件设计成一种计算方法;把反应中焓和熵的能量变化设计成目标函数,通过求目标函数的最优组合来实现问题的求解。在现实生活中有许多问题都是求最优组合问题,它的求解可以采用人工化学反应优化算法来实现,但求解这些问题就是求解0-1背包问题,也是计算机领域的NP难问题,所以提出一种混合人工化学反应优化算法求解0-1背包问题。该方法首先把化学反应分成单分子和双分子两种反应类型,并对这两种类型中的不同化学反应进行二进制编码;其次,为了获得问题的最优解,引入一个贪婪策略的修正算子来修正反应过程的随机选择所产生的非可行解,并通过局部和全局搜索来获得问题的最优求解。实验结果证明ACROA算法的性能明显优于GA算法和QEA算法,该算法在解决背包问题等有很大的优势。

摘要：
ITUbee is the lightweight encryption algorithm that was proposed by the second International Symposium on lightweight encryption security and privacy in 2013. It is based on the Feistel network. We optimized S-box, round function and round constant addition. The optimized round constant is the variable which is converted from the related round number i. There is no need to allocate area resource for it. The experimental results show that the throughput of the optimized ITUbee algorithm reaches 364.695ÂMb/s. The area is reduced to 10650 Slices. We studied and implemented the masking ITUbee algorithm to resist power analysis attack. The implemented performance is also compared. The area of the masking ITUbee is increased by about 4%. The clock frequency is raised from 100.291ÂMHz to 102.396ÂMHz, throughput is increased from 364.695ÂMb/s to 372.349ÂMb/s. © Springer Nature Switzerland AG 2020.

摘要：
In order to against the side channel analysis attack such as power, electromagnetic waves, and time attack, an optimized masking method is proposed for Advanced Encryption Standard (AES) algorithm in this paper. This scheme adopts random hamming distance mask and offset randomization strategy in the first two rounds, the last round and two rounds randomly selected in the middle of the AES algorithm to ensure the security of each intermediate value. The scheme then adopts fixed-value mask strategy in the five rounds in the middle, which can reduce the time and space consumption to recalculate S box, improve the efficiency of the algorithm and reduce the production cost. To compare with other defence methods, we build a power analysis platform and conduct extensive experiments. The experimental results show that our optimized AES masking method is more secure than the compared methods, and it is able to resist second-order correlation power analysis (CPA) attacks. © Springer Nature Switzerland AG 2020.

Binary firefly algorithm;Discrete optimization;Meta-heuristics;Minimum labeling spanning tree problem
摘要：
Given a connected undirected graph G whose edges are labeled, the minimum labeling spanning tree (MLST) problem is to find a spanning tree of G with the smallest number of different labels. The MLST is an NP-hard combinatorial optimization problem, which is widely applied in communication networks, multimodal transportation networks, and data compression. Some approximation algorithms and heuristics algorithms have been proposed for the problem. Firefly algorithm is a new meta-heuristic algorithm. Because of its simplicity and easy implementation, it has been successfully applied in various fields. However, the basic firefly algorithm is not suitable for discrete problems. To this end, a novel discrete firefly algorithm for the MLST problem is proposed in this paper. A binary operation method to update firefly positions and a local feasible handling method are introduced, which correct unfeasible solutions, eliminate redundant labels, and make the algorithm more suitable for discrete problems. Computational results show that the algorithm has good performance. The algorithm can be extended to solve other discrete optimization problems. © 2020 Tech Science Press. All rights reserved.
