The heat transfer mechanism of hollow glass microsphere/epoxy resin composites (HGM/ER) is intricate, and the formation of void structures during material preparation complicates the prediction of thermal conductivity. To investigate the microscopic heat transfer mechanisms of HGM/ER materials with void structures and analyze the impact of void variables on the overall thermal performance, this study addresses the issue of low packing density and poor uniformity in traditional cellular unit structures. An improved random sequential adsorption (rsa) algorithm is proposed, increasing the upper limit of particle fill rate by 25% relative to traditional rsa algorithms. The Benveniste equivalent microsphere thermal conductivity model is selected for thermal performance simulation, demonstrating its high correlation with the three-component model (air, glass, resin), with a maximum relative error of only 1.32%. A classification method for void types in HGM/ER materials is proposed, categorizing them into interfacial and free voids. The microscopic heat transfer mechanisms of HGM/ER materials are investigated under different voids levels and void types, and it was found that the effect of interfacial voids on thermal conductivity is 60% higher than that of free voids. Based on the measured voids of the material, this study provides a reference for the convenient prediction of thermal conductivity in practical engineering applications of HGM/ER composites.

Steganography is the technique of hiding any secret information like text, image or video behind a cover file. Audio steganography is one of the widespread data hiding techniques that embeds secret data in audio signals. The secret data is hidden in a way that unauthorized people are not aware of the existence of the embedded data and without changing the quality of the audio signal (cover audio). Data hiding in audio signals has various applications such as protection of copyrighted audio signals, secret communication, hiding data that may influence the security and safety of governments and personnel. This paper proposes an efficient steganography scheme based on sample comparison in Discrete Wavelet Transform (DWT) domainwhere the cover audio is decomposed into several multi sub-bands, and then selected coefficients of details are changed by a threshold value depending on the embedding cipher image bit. This approach employs an original image component to perform rsa encryption on it, then cipher bits are embedded in the details components of the audio signal according to a predetermined threshold value. The performance of the algorithm has been estimated extensively against attacks, and simulation results are presented to prove the robustness of the proposed algorithm.

The vulnerabilities of the rsa cryptographic algorithm are analyzed, and it is not securely implemented. As the simultaneous multithreading could enable multiple execution threads to share the execution resources of a superscalar between the chipper process and the spy process, the shared access to memory caches provides an easily used high bandwidth covert channel between threads, allowing that a malicious thread can monitor the execution of another thread. This paper targets at rsa algorithm which is implemented with sliding window exponentiation algorithm via OpenSSL, the attacker can monitor the cryptographic thread by executing a spy thread, recording the timing characteristic during the rsa decryption when reading the Cache. The attacker can recover the original key via analyzing these timing measurements. Finally, the authors provide some countermeasures of how this attack could be mitigated or eliminated entirely.

Aiming at the limitation of one-dimensional Chebyshev chaotic map, an improved two-dimensional Chebyshev chaotic map is proposed. This map makes its structure more complex by extending the original one-dimensional map to a high-dimensional map and adding system parameters. Then, the introduction of the sine function further increases the computational complexity of the mapping. Aiming at the periodic shortcoming of traditional Arnold scrambling, the non-linear improvement of its scrambling equation is carried out to make it have better scrambling characteristics. Based on the improved Chebyshev map and the improved Arnold scrambling equation, a digital image encryption algorithm is proposed. Experimental results show that the proposed encryption algorithm can effectively resist plaintext attack, differential attack, statistical analysis and other attacks.

The security of rsa algorithm depends upon the positive integer N, which is the multiple of two precise large prime numbers. Factorization of such great numbers is a problematic process. There are many algorithms has been implemented in the past years. The offered KNJ-Factorization algorithm contributes a deterministic way to factorize rsa N=p*q. The algorithm limits the search by only considering the prime values. Subsequently prime numbers are odd numbers (apart from 2) accordingly it also requires smaller number steps to factorize rsa. In this paper, the anticipated algorithm is very simple besides it is very easy to understand and implement. The main concept of this KNJ-factorization algorithm is, to check only those factors which are odd and prime. The proposed KNJ-Factorization algorithm works very efficiently on those factors;which are adjoining and close to root N. The proposed factorization method can speed up if we can reduce the time for primality testing. It fundamentally decreases the time complexity.

This paper presents Hybrid (rsa & AES) encryption algorithm to safeguard data security in Cloud. Security being the most important factor in cloud computing has to be dealt with great precautions. This paper mainly focuses on the following key tasks: 1. Secure Upload of data on cloud such that even the administrator is unaware of the contents. 2. Secure Download of data in such a way that the integrity of data is maintained. 3. Proper usage and sharing of the public, private and secret keys involved for encryption and decryption. The use of a single key for both encryption and decryption is very prone to malicious attacks. But in hybrid algorithm, this problem is solved by the use of three separate keys each for encryption as well as decryption. Out of the three keys one is the public key, which is made available to all, the second one is the private key which lies only with the user. In this way, both the secure upload as well as secure download of the data is facilitated using the two respective keys. Also, the key generation technique used in this paper is unique in its own way. This has helped in avoiding any chances of repeated or redundant key.

The Internet is developing rapidly, which leads to a sharp increase in information transmitted by the network. Moreover, people have a higher demand for encrypting meetings and encrypting information transmission. Currently, the data encryption technologies used in network transmission mainly include symmetric encryption algorithms, asymmetric encryption algorithms, virtual network encryption technology, SSL protocol encryption, etc. However, the widely used symmetric encryption algorithm has some problems, such as complex distribution and complicated management of keys, while the asymmetric encryption algorithm generally has the disadvantages of slow encryption and decryption speed. The research and analysis of the typical symmetric encryption algorithm DES and asymmetric encryption algorithm rsa are studied to address this issue. This paper puts forward mixed cryptogram arithmetic of DES and rsa. The principle of the algorithm is that the sender encrypts the key of DES with rsa's public key and then encrypts the plaintext with the new longer key by DES. The receiver can decrypt the encrypted key and ciphertext to obtain plaintext. The advantage of this hybrid algorithm is that rsa only needs to encrypt the short key of DES. Therefore, the encryption speed is improved greatly, and a longer new key is obtained, which makes the encryption result of DES more secure and reliable. The hybrid algorithm shows good performance through the code implementation and analysis of the results. Not only the encryption speed is fast, but the security is also guaranteed, and it has a favorable application prospect in digital signature and other fields. © 2023 IEEE.
