Abstract:

The objective of the study is to introduce a novel hybrid encryption scheme, combining both symmetric and asymmetric encryptions with a data shuffling mechanism, to enhance data obfuscation and encryption security. The approach uses RSA for asymmetric encryption and ChaCha20-Poly1305 for symmetric encryption. To increase the complexity, an additional phase involves reorganizing the RSA-encrypted data blocks. Furthermore, symmetric key generation using the key derivation function is employed to generate the key for symmetric encryption through an asymmetric private key. Decryption entails rever

Abstract:

In this paper, a hybrid encryption is proposed using combination of two asymmetric schemes. The existing schemes are lacking in encrypting large data files, there time complexity may worsen with size. In this work the homomorphic algorithm is used along with RSA, to enhance the encryption and decryption time. The evaluation study has been done between AES, 3DES, DES and proposed algorithm on basis of their time complexities. Our proposed work has very least complexity for both encryption and decryption. Proposed scheme is also highly secure as it involves 2 encryption and decryption rounds.

Abstract:

Data encryption technology is a key method to secure sensitive data. The privacy and confidentiality of data is protected by encrypting the data, i.e., transforming the original data into a form that cannot be understood without authorization. However, the security of traditional encryption algorithms is gradually challenged with the increase in computing power. Therefore, studying how to apply more advanced encryption techniques has become a current research hotspot. This study aims to analyze the application of data encryption techniques and explore the advantages and applicability of emergi

Abstract:

Recently, medical image encryption has gained special attention due to the nature and sensitivity of medical data and the lack of effective image encryption using innovative encryption techniques. Several encryption schemes have been recommended and developed in an attempt to improve medical image encryption. The majority of these studies rely on conventional encryption techniques. However, such improvements have come with increased computational complexity and slower processing for encryption and decryption processes. Alternatively, the engagement of intelligent models such as deep learning a

Abstract:

Cryptographic encryption mechanisms in the open source PostgreSQL server DBMS are discussed. Special high-level and low-level functions of symmetric encryption of the Pgcrypto module for ensuring information security of data are analyzed. The analysis of special functions of the third-party GPG program is performed, which allow performing asymmetric encryption in the PostgreSQL database server. A combined data encryption technology in database tables is proposed, using a hierarchy of keys (asymmetric and symmetric encryption) with a passphrase, which is also encrypted to ensure better protecti

Abstract:

Internal auditing demands innovative and secure solutions in today’s business environment, with increasing competitive pressure and frequent occurrences of risky and illegal behaviours. Blockchain along with secure databases like encryption improves internal audit security through immutability and transparency. Hence integrating blockchain with homomorphic encryption and multi-factor authentication improves privacy and mitigates computational overhead. Recently, blockchain applications for internal audits in the enterprise sector are still emerging. Thus, blockchain technology in auditing prov

Abstract:

In this paper we consider for the first time the possibility of applying the tridiagonal runthrough formulas for text data encryption. The encryption algorithm consists in computing the right part of a linear algebraic equations system with a tridiagonal matrix. In the problem, all the equations coefficients, the right-hand side and the solution take the values of the residues modulo a prime number p. The decryption algorithm consists in solving the SLAE on the class of prime modulo p deductions. The decryption algorithm uses the tridiagonal run method. Two theorems are proved for the algorith
